----------------------------------------------------------------------- Protein Data Bank Quarterly Newsletter Number 65 October 1993 ----------------------------------------------------------------------- October PDB Release Includes 523 New Full-Release Entries We are pleased to announce that the October 1993 PDB release includes 523 new full-release entries. In addition, all prerelease entries have now been converted to full-release entries this summer, including 230 newly-deposited entries that were processed directly into full release. Full-release ver- sions of the 322 structures still in prerelease form on the Octo- ber CD ROM and magnetic tape release are now in the final checking stages. Some of these entries have recently been approved for release. Others are still waiting for release approval. We expect that shortly all will be ready and loaded on the PDB FTP server. A significant amount of new software has been installed recently by PDB to assist with data processing and checking. For example, the program PDBINFO written by David Hinds from Michael Levitt's laboratory at Stanford University Medical Center is now being used extensively to check PDB entries for syntax violations. Additional software was implemented to automate a variety of processing tasks and to improve our quality control, ensuring stricter adherence to PDB's pub- lished specifications. We will shortly be using this software to assist in checking for errors in older entries included in prior PDB releases. The number of entries processed for the October release reflects a large increase compared to previous PDB releases, which added at most 50 - 100 new structures to the database. Significant gains in data processing productivity have been achieved, enabling PDB to respond to the challenge posed by the exponentially growing number of structure submissions. The successful completion of the work done this summer has been possible only through the outstanding dedication and commitment of the PDB staff as well as with the assistance of our depositors who have been extremely helpful in resolving outstanding questions about their entries. In our continuing effort to improve the process of entering new structures into the PDB, we are actively soliciting software from the user community. If you have data preparation or checking programs that you are willing to share, please con- tact PDB directly at the address given on the last page of this Newsletter. ----------------------------------------------------------------------- October 1993 PDB Release 1727 full-release atomic coordinate entries (523 new additions) 1564 proteins, enzymes and viruses 137 DNA's 7 RNA's 9 tRNA's 10 carbohydrates 322 prerelease atomic coordinate entries 345 structure factor entries 31 NMR experimental entries The total size of the atomic coordinate entry database is 547 Mbytes, uncompressed. ----------------------------------------------------------------------- PDB Management Tom Koetzle has recently resigned as Head of PDB, after announcing his intention to do so earlier this year. Tom remains at Brookhaven as an active member of the Chemis- try Department and has graciously agreed to act as a consult- ant for the new PDB management. We all appreciate Tom's dedication to making PDB the resource that it is today and wish him well in his research endeavors. Since a permanent replacement for Tom has not yet been found, Brookhaven's management has asked me to serve as Acting PDB Senior Project Manager. My background is in the field of computing, having been a member of the Computing and Communications Division (CCD) at Brookhaven for nine- teen years before joining PDB six months ago. At CCD, I was involved in the design and implementation of the Laboratory- wide network which consists of over 2000 nodes. More recently at PDB, I have been involved in building CIF tools and providing better access to the database. I look forward to working with all of you and the PDB staff in actively guiding PDB toward the incorporation of CIF, auto- mated deposition, and new methods of data access to the PDB. I intend to provide the permanent project manager with a vibrant and forward-looking organization. Please let me know if I can do anything to assist you in your use of the PDB or if you have any ideas that would make this service more valuable. You can reach me via e-mail at stampf@bnl.gov or by telephone through our main number at 516-282-3629. - Dave Stampf ----------------------------------------------------------------------- Staff News We are pleased to announce the appointment of Dejun Xue, Minette Cummings, and Michael Libeson to the PDB staff. Dejun joins the software development team and is currently involved in efforts to convert PDB into the macromolecular CIF format. Minette and Michael join the database production staff where their responsibilities include assisting in the prep- aration of newly deposited entries for distribution. This summer, a number of temporary staff members assisted PDB in the work of converting prerelease entries into full- release form. In particular, we wish to acknowledge the con- tributions of Laura Hildebrand, Racquel Ponce and Barbara Roland toward the successful completion of this project. We also wish to acknowledge significant contributions by our summer students, Mingyu Xu of the University of Southern Maine and Eugene Koh of Harvard University. Mingyu assisted in the preparation of newly deposited entries and Eugene wrote the PC-Windows database application pro- gram PDB-Shell. Joe Christian, who joined PDB in 1990 as a summer student and later became a member of the database production group, has left Brookhaven to pursue his career goals in the music field. Joe's primary responsibility was to accept newly deposited entries. He also wrote a number of programs that helped automate PDB data processing. We wish Joe success in his new endeavor. ----------------------------------------------------------------------- Attention Windows Users --- PDB-Shell PDB is pleased to announce a new facility for Windows users to access and display structures from the PDB. This new facility is called PDB-Shell and is available on the October 1993 CD-ROM and on the PDB anonymous FTP server. PDB-Shell allows the user to search the database for various criteria such as ident code, accession date, compound name, and author. These criteria can be combined to further restrict or expand search results. A list of all search results is dis- played. A short description of each structure is easily obtained, and a facility is provided to display the entire ASCII text of each coordinate entry file. Additionally, each structure can be viewed using RasMol graphics software which is inte- grated into PDB-Shell. Features supported by RasMol, which was written by Roger Sayle at the University of Edinburgh, Scotland, include the ability to rotate a structure, color individ- ual atoms for ready identification, and represent a structure as balls and sticks or in spacefill fashion. The default access is from the CD-ROM, but PDB-Shell can easily be configured to allow access from a hard disk, or network mounted file sys- tem. ----------------------------------------------------------------------- CD-ROM Information PDB releases are available on CD-ROM in ISO 9660 format. The layout of files on the CD-ROM mirrors the UNIX tape dis- tribution and uses the tape01, tape02, ..., tapeN subdirecto- ries. The entry files are ASCII format and are readable by software able to read text files. PDB-Shell, a new facility for Windows users to access and display structures from the PDB database, is now available on our CD-ROM. As was described in the preceding article, PDB- Shell allows the user to search the database for various crite- ria such as ident code, accession date, compound name, and author. The PDB CD-ROM also includes the MAGE and PREKIN structure display and manipulation software by David Richard- son and Jane Richardson of Duke University [The Kinemage: A Tool for Scientific Communication. Protein Science 1, 3-9 (1992)] in both PC and Macintosh versions. VAX/VMS systems currently do not directly support access to ISO 9660 CD-ROMs. The PDB CD-ROM may be accessed on VAX/VMS systems using either of the following approaches: 1. There is an ISO 9660 compliant device driver available from Digital Equipment Corporation (DEC) that allows direct access to the CD-ROM (driver part number YT- GS001-01). Please contact your DEC sales representa- tive for further information. 2. There is a public utility for accessing ISO 9660 CD- ROMs, called CD_ACCESS, written by Peter Stockwell, University of Otago, New Zealand, that will allow all the files on the CD-ROM to be copied to a magnetic disk drive. This utility can be obtained from the EMBL e-mail server (for further information you may contact DataLib@EMBL-Heidelberg.DE). When copying files using CD_ACCESS, be sure to use the /BINARY qualifier to the copy command. The CD-ROM does not mount properly on Silicon Graphics systems running IRIX version 4.0.1. To resolve this problem, you need to upgrade to version 4.0.2 or higher. Because of limitations on symbolic links with ISO 9660 CD- ROMs, we were unable to provide a directory on the CD- ROMs pointing to all files in the various "tape" subdirectories. Therefore, we recommend that you do so from a directory on one of your local disk filesystems. Further detailed instruc- tions are included in an enclosure sent with each CD-ROM order. ----------------------------------------------------------------------- Procheck Software Package We are pleased to announce that the Procheck software package is being made available for electronic distribution from PDB. Oxford Molecular, Ltd. and PDB have agreed that upon receipt of a signed license agreement at PDB, the source and documentation for Procheck will be made avail- able free of charge. The Procheck software package, created by J. M. Thornton, M. W. MacArthur, R. A. Laskowski and D. S. Moss, performs evaluations of the stereochemical qual- ity of protein structures. In order to acquire a copy of Procheck, you must obtain the license agreement, copies of which are available via the PDB FTP, gopher, or file server in the file called procheck-license. You must complete and sign this license agreement and return it to PDB (Protein Data Bank Procheck License, Chemistry Department--Bldg. 555, Brookhaven National Lab- oratory, P.O. Box 5000, Upton, NY 11973-5000 USA). Once we have your signed agreement, we will either e-mail the source to you or place it on the machine of your choice via FTP. Your signed license agreement will be forwarded to Oxford Molecular who will keep you up to date about further developments. All queries concerning the software should be directed to Steve Gardner, Macromolecular Product Man- ager, Oxford Molecular, Ltd., The Magdalen Centre, Oxford Science Park, Sanford-on-Thames, Oxford, England OX4 4GA (Telephone: +44-865-784600). ----------------------------------------------------------------------- CIF Advances In April representatives from PDB traveled to York, England to participate in a CIF workshop sponsored by a joint EC/USA initiative. Eleanor Dodson of the University of York hosted the workshop. At the York workshop, the participants helped to reformulate the CIF macromolecular dictionary in order to allow a more database-like access to the information. In October a second meeting sponsored by the NSF and hosted by Phil Bourne was held in Tarrytown, New York where many of the same participants showed the advances made in software and in the design of the dictionary. Since then, PDB is taking an active role in shaping the conversion of our database from the traditional PDB format to a more modern CIF representation. We anticipate rolling out many software tools over the next six to nine months to help our users cope with this change. It is our intention to completely hide any of the CIF internals from the PDB user. ----------------------------------------------------------------------- ACA Meeting It was great to see all of our users and depositors who visited the PDB's exhibit at the American Crystallographic Associa- tion (ACA) Annual Meeting held in Albuquerque, New Mexico from May 23 through May 28. Many also attended a session at the meeting on "Macromolecular Databases" that was chaired by Keith Watenpaugh, current Chairman of PDB's Advisory Board. At Albuquerque, PDB presented the first public demonstra- tion of its new MAKEPDB data input procedure. MAKEPDB allows depositors to check their own entries before submitting them using PDB's structure evaluation procedures and Janet Thornton et al.'s PROCHECK package. The response to MAKEPDB at Albuquerque was very enthusiastic, and we want to encourage depositors to try this new procedure and help us by giving suggestions for its improvement. Check the PDB e-mail server and FTP site for further information. ----------------------------------------------------------------------- IUCr Beijing Congress About 1,800 crystallographers from around the world gath- ered in Beijing in late August for the XVI Congress and Gen- eral Assembly of the International Union of Crystallography (IUCr). PDB was represented at the Congress by Tom Koet- zle and John Rose. With the help of the Beijing Local and Program Committees, a very successful workshop on the PDB was staged at which John Rose gave demonstrations of PDB procedures on a Silicon Graphics workstation loaned to us by Peking University. Tom Koetzle also gave a talk on the status and future of PDB at the Crystallographic Databases microsymposium. The Congress provided an opportunity to speak with many individuals interested in the PDB, including quite a number who had no previous direct contact with the database. More than fifty complementary PDB CD-ROM's were distributed during the meeting. The Congress was an overwhelming success, highlighted by a rich and varied sci- entific program. We will not forget the warm hospitality extended to us by our Chinese hosts! ----------------------------------------------------------------------- Deposition Form and Guidelines for Deposition A set of guidelines helpful to use when preparing an entry for submission to PDB is available via the PDB FTP server. These guidelines address issues of representation that often arise in the preparation of coordinates for distribution. For example, the document includes an explanation of how PDB represents entries with multiple chains. Also included is advice on how to avoid errors commonly found in new depo- sitions. Submitted entries that follow these guidelines take less time to process, expediting the prompt issuance of ident codes. PDB strongly recommends that depositors review the docu- mented guidelines in order to facilitate the deposition pro- cess. In the coming months, PDB plans to revise the deposition form. Therefore, it is important that a new copy be retrieved from the PDB FTP before each deposition. Docu- ments are available via anonymous FTP and gopher from pdb.pdb.bnl.gov, via our file server, and in printed form upon request. ----------------------------------------------------------------------- Distribution of Obsolete Entries Over the years a number of PDB entries have been with- drawn by the depositors, usually because improved data was available or, less frequently, because a serious problem was discovered with the data. Entries that were withdrawn before their public release will not be distributed by PDB except by the express permission of the depositor. Entries that were withdrawn following their release exist on old PDB distribution tapes and are stored in numerous laboratories that have received these data from Brookhaven. In the near future, we plan to make these obsolete data available to all those who may wish to make use of them. We anticipate that the obso- lete entries will be of interest to individuals studying new approaches to solving or refining structures and needing `problem' cases with which to evaluate their methods, and to those interested in the evolution of the PDB database over time. Watch the PDB e-mail file server and FTP site for announcements on how to access the obsolete entries. All obsolete entries will be prominently flagged to distinguish them from current PDB entries. Any publication that may result from the use of obsolete entries should include an explicit statement that the entries in question have been with- drawn and/or replaced. ----------------------------------------------------------------------- 1600 cpi Tapes Discontinued Due to the fact that there is very little demand for distribution of data on 1600 cpi reel tapes, PDB has decided to discon- tinue their distribution as of October 1, 1993. We encourage those who may have ordered 1600 cpi tapes in the past to switch to one of the alternative tape formats, all of which have much higher capacity, are more economical, and are much less time-consuming to load. ----------------------------------------------------------------------- Internet Access to PDB Access by Gopher ---------------- PDB is accessible using Gopher software which follows a simple protocol to "tunnel" through a TCP/IP Internet. Gopher is recommended for obtaining information and files from PDB. The following excerpts are from the PDB's Gopher FAQ (Frequently Asked Questions) listing. Q: What is Gopher? A: The Internet Gopher client/server provides a distributed information delivery system around which a world/ campus-wide information system (CWIS) can readily be constructed. While providing a delivery vehicle for local information, Gopher facilitates access to other Gopher and information servers throughout the world. Q: Where can I get Gopher software? A: Via anonymous FTP to boombox.micro.umn.edu. Look in the directory /pub/gopher. Q: What do I need to access Gopher? A: You will need a gopher "client" program that runs on your local PC or workstation. There are clients for the following systems. The directories listed show the location of each client on the anonymous FTP site boombox.micro.umn.edu (134.84.132.2) in the directory/pub/gopher. Unix Curses & Emacs : /pub/gopher/Unix/gopher1.12.tar.Z Xwindows (athena) : /pubrs/gopher/Unix/xgopher.1.2.tar.Z Xwindows (Motif) : /pub/gopher/Unix/moog Xwindows (Xview) : /pub/gopher/Unix/xvgopher Macintosh Hypercard : /pub/gopher/Macintosh-TurboGopher/old- versions/* Macintosh Application : /pub/gopher/Macintosh-TurboGopher/* DOS w/Clarkson Driver : /pub/gopher/PC_client/ NeXTstep : /pub/gopher/NeXT/ VM/CMS : /pub/gopher/Rice_CMS/ or /pub/gopher/VieGOPHER/ VMS : /pub/gopher/VMS/ OS/2 2.0 : /pub/gopher/os2/ MVS/XA : /pub/gopher/mvs/ Many additional clients and servers have been developed by others. Gopher allows users easy access to various types of data residing on multiple hosts. The user is the "client" who makes queries to a "server" residing on another host on the Internet network. This system has been set up so that users do not need to know the location of servers, since Gopher transparently handles the connections. The PDB Gopher server allows access, search, and downloading of the same information and coordinate files as does anonymous FTP, but through a windowed or menu environment. Merely choose "Protein Data Bank FTP Site" after opening Gopher. "Full-text search of PDB" allows one to search the PDB using either an ident code, author name, compound name, or any other term. Information for setting up an Internet Gopher client including source files for different machines is available via anonymous FTP to boombox.micro.umn.edu (134.84.132.2) under the directory /pub/gopher. Users running a Gopher client can access the PDB server by including the following link: Name = Protein Data Bank FTP site Type = 1 Host = pdb.pdb.bnl.gov Port = 70 Path = 1/ For more information or help in accessing the PDB via Gopher, send e-mail to oeder@bnl.gov. Access by File Server --------------------- The PDB e-mail file server is available for all users. In addition to the atomic coordinate entry files, PDB general information and documentation may be requested via e-mail. For more information on the e-mail file server, send an e-mail message to: fileserv@pb1.pdb.bnl.gov (with no subject line). Be sure to include the following text: send info name@machine_name. Access by Anonymous FTP ----------------------- PDB has an anonymous FTP account on the computer sys- tem pdb.pdb.bnl.gov (Internet address 130.199.144.1). Files may be transferred to and from this system using anonymous as the FTP user name and your e-mail address as the pass- word. Besides downloading entries, data files, and documen- tation, it is possible to upload any files that you may wish to send to PDB. Please note that those using VMS may need to place quotes around file names. How to Login Using FTP ---------------------- To use the FTP command to transfer files to and from PDB, you must first login to PDB using FTP. The following example shows how to use FTP to connect to the computer system pdb.pdb.bnl.gov. Start the program by typing: ftp pdb.pdb.bnl.gov The screen display will be similar to this: Connected to pdb.pdb.bnl.gov. 220- 220 pdb.pdb.bnl.gov FTP server ready. If the user name prompt comes up, type anonymous as the user name for the prompt that appears. The user name anon- ymous must be used: Name (pdb:your_name): anonymous If the user name prompt does not come up automatically, type: user and it will come up. Appearing next will be the password prompt. Type your e-mail address (name@machine_name): 331 Guest login ok, type your name as password. Password:joe_doe@foobar.crash.edu You are logged in when the screen displays: 230 Guest login ok, access restrictions apply. and prints the login README file to your screen. File Transfers Using FTP ------------------------ Once you are logged on PDB using FTP, you can transfer files to and from your system using the put and get commands. This example shows how to transfer a file named jan93news- letter.txt to your machine. Type the following at the FTP prompt after you login using FTP: ftp> ls -l 200 PORT command successful. 150 Opening ASCII mode data connection for '/bin/ls'. total 602 -rw-r--r-- 1 root 3019 Mar 9 ADVISORY.NOTICE -rw-r--r-- 1 root 1805 Mar 9 README drwxr-xr-x 2 root 512 Feb 24 asn_1 drwxr-xr-x 2 root 512 Feb 24 bin drwxr-xr-x 2 root 512 Mar 17 crystallographer_info drwxr-xr-x 2 root 512 Feb 24 dihdrl drwxr-xr-x 2 root 512 Feb 24 etc drwxr-xr-x 4 root 512 Mar 5 fullrelease drwxr-xr-x 2 root 512 Feb 24 hassp drwxr-xr-x 2 root 512 Mar 8 index -rw-r--r-- 1 root 281791 Apr 2 ls-lR drwx-wx-wx 2 root 3584 Apr 9 new_uploads drwxr-xr-x 2 root 1024 Mar 10 newsletter drwxr-xr-x 4 root 10240 Mar 25 prerelease drwxr-xr-x 6 root 1024 Mar 5 program_tape drwxr-xr-x 2 root 512 Mar 29 pub drwxr-xr-x 3 root 512 Mar 5 structure_factors 226 Transfer complete. remote: -l 1111 bytes received in 0.16 seconds (6.6 Kbytes/s) ftp> cd newsletter 250 CWD command successful. ftp> ls -l 200 PORT command successful. 150 Opening ASCII mode data connection for '/bin/ls'. total 1082 l--------- 1 root 18 Mar 5 ADVISORY.NOTICE -rw-r--r-- 1 root 8549 Mar 16 README -rw-r--r-- 1 root 1072 Jan 25 jan93avail_on_tape.txt -rw-r--r-- 1 root 4408 Jan 25 jan93biblio.txt -rw-r--r-- 1 root 2042 Jan 25 jan93corrections.txt -rw-r--r-- 1 root 67979 Jan 25 jan93entries.txt -rw-r--r-- 1 root 176090 Mar 5 jan93fulltables.txt -rw-r--r-- 1 root 163990 Mar 10 jan93newsletter.ps -rw-r--r-- 1 root 27096 Mar 29 jan93newsletter.txt -rw-r--r-- 1 root 1850 Jan 25 jan93nmr.txt -rw-r--r-- 1 root 5946 Jan 25 jan93onhold.txt -rw-r--r-- 1 root 70478 Jan 25 jan93pending.txt -rw-r--r-- 1 root 2205 Jan 25 jan93prog_misc.txt -rw-r--r-- 1 root 19449 Jan 25 jan93struct_fact.txt 226 Transfer complete. remote: -l 1049 bytes received in 0.12 seconds (8.7 Kbytes/s) ftp> get jan93newsletter.txt 200 PORT command successful. 150 Opening ASCII mode data connection for 'jan93newsletter.txt' (27096 bytes).226 Transfer complete. local: jan93newsletter.txt remote: jan93newsletter.txt 27787 bytes received in 0.16 seconds (1.7e+02 Kbytes/s) This copies the file named jan93newsletter.txt from PDB to your computer. To copy a file from your system to PDB, login using FTP and type: ftp> cd new_uploads 250 CWD command successful. ftp> put dataFROMjoedoe 200 PORT command successful. 150 Opening ASCII mode data connection for 'dataFROMjoedoe'. 226 Transfer complete. local: dataFROMjoedoe remote: dataFROMjoedoe 554 bytes sent in 0.0078 seconds (69 Kbytes/s) This copies the file named dataFROMjoedoe from your sys- tem to the PDB file upload directory. Be sure to include infor- mation in the header of the file stating what it is and who you are. The FTP program has many options. See the manual page for FTP ("man ftp") for further details. ----------------------------------------------------------------------- Depositing Data with PDB PDB accepts depositions of atomic coordinates, bibliographic citations, primary sequence and secondary structure informa- tion, as well as crystallographic structure factors, and NMR experimental data on biological macromolecules. These may include proteins, RNA, DNA, viruses, and carbohydrates. Deposited data are processed with PDB verification and checking programs, converted to a standard format, archived, and distributed worldwide. A deposition has three essential components which must be received before a submission can be processed: the com- pleted deposition form, relevant reprints and preprints, and the actual data in PDB format. The deposition form can be submit- ted electronically or on paper. Data must be submitted in machine-readable form via anonymous FTP, e-mail, magnetic tape, or disk. A deposition form and more information on depositing entries is available in the FTP directory /pub and via the PDB e-mail file server. You can also request these items by phone, fax, or surface mail. ----------------------------------------------------------------------- Obtaining A New Entry's Ident Code The ident code of a new entry will be issued only after the complete deposition is received and initial screening verifies the correctness and integrity of the entry. After processing is complete, a letter providing the ident code and requesting approval for release is sent to the depositor. To facilitate assignment of an ident code, it is necessary that the deposition include all applicable information, including any preprints or reprints of journal articles referenced. Data must be in PDB format, and the deposition form must be legible and complete. Many depositors have found that by submitting their entry to PDB at the same time that they submit their paper to a scientific journal, publication delays can be avoided. In the future, PDB will be implementing procedures giving depositors direct access to PDB processing and checking pro- grams via Internet. Depositors using these new procedures can expect to receive confirmation of their deposition along with the entry ident code within three days of submission. When the new procedures are implemented, further instruc- tions will be available via anonymous FTP and in future num- bers of this Newsletter. ----------------------------------------------------------------------- Finding An Existing Entry's Ident Code Each PDB entry is uniquely identified by an ident code. There- fore, retrieving the file for a particular structure requires this ident code. Lists of newly received entries are published quar- terly in the PDB Newsletter. Tables of all PDB entries can be obtained via anonymous FTP and e-mail server or by normal mail upon request. Within the anonymous FTP account are two subdirectories which are useful for locating ident codes. The first is /index. This contains the following files generated from the latest release: author.lst ident codes and authors compound.lst ident codes, resolutions, and compound names crystal.lst ident codes, unit cell dimensions, space groups, and Z's resolu.lst ident codes and resolutions source.lst ident codes and sources The second useful subdirectory is /newsletter. This contains text (.txt) and PostScript (.ps) files of the full tables listing all currently available entries and pending entries that are in preparation for future release. Retrieving files from these two subdirectories, as well as the directory listings which are in files named 'ls-lR', allows you to determine whether the mole- cule of interest is available, what its ident code is, and where it is located. Please be aware that files can be downloaded while in FTP, but they cannot be viewed on the terminal while within this program. Therefore, it is sometimes helpful to download tables or directory listings, quit FTP, determine which addi- tional files you want to retrieve, then reconnect to the FTP site to get them. If you are logged in from a UNIX computer, after retrieving a file you may view its contents by escaping to the shell with the command '! cat filename' or '! more filename', where cat and more are UNIX commands. ftp> get ls-lR (retrieves the file named ls-lR) ftp> !cat ls-lR (types the local file 'ls-lR') ftp> !more ls-lR (types the local file 'ls-lR', one page at a time) The PDB e-mail file server or Gopher are other methods to locate PDB ident codes. Please see detailed information about these services on pages 4-5. Finally, in some cases, journal articles reporting results of structural analyses of bio- logical macromolecules provide the PDB ident code. ----------------------------------------------------------------------- Affiliated Centers Eleven affiliated centers offer DATAPRTP for distribution. These centers are members of the Protein Data Bank Ser- vice Association (PDBSA). Centers designated with an as- terisk(*) distribute DATAPRTP on magnetic media; those without an asterisk are on-line DATAPRTP distributors.
