EM Data Bank to join the PDB archive
The EM Data Bank (EMDB), the primary archive for
experimentally-determined maps obtained using three-dimensional
electron microscopy methods, will join the PDB archive (ftp://ftp.wwpdb.org)
on 7 March 2012.
The merger marks an important milestone in the
Worldwide Protein Data Bank's
mission to maintain a single public archive of macromolecular
structural data from all structure determination methods that is
freely available to the global community. The PDB currently
has over 77000 coordinate entries, nearly all with associated
experimental data, including 57000 X-ray entries with structure factor files and 6400 NMR
entries with restraints. The merger will join all 3DEM results into a
single archive, including over 1200 electron microscopy derived
maps currently held in EMDB with coordinates for 400 EM
map-derived models in PDB, and is an essential step in the wwPDB's
development of a Common Deposition & Annotation Tool that will cover all
experimental methods, including hybrid methods.
With the addition of EMDB data, the physical size of the complete wwPDB
archive will jump from its current 130 GB to roughly 180 GB.
Sites that mirror the full wwPDB archive will need to increase
storage capacity accordingly.
The main impact for 3DEM data users will be the change in download links for maps.
However, 3DEM depositors will not be directly affected--map and model
deposition sessions should continue to be initiated from
EMDataBank.
All 3DEM map depositions will continue to receive
EMDB IDs and all 3DEM coordinate entries will continue to receive
PDB IDs.
The Worldwide Protein Data Bank partners are organizations that
act as deposition, data processing and distribution centers for
PDB data. The founding members are RCSB PDB (USA), PDBe (Europe)
and PDBj (Japan). The BMRB (USA) group joined the wwPDB in 2006.
The EMDB was established in 2002 by PDBe at the European
Bioinformatics Institute, and is currently operated by
EMDataBank, Unified Data Resource for 3DEM,
established in 2007 as a joint effort of PDBe, RCSB
PDB and NCMI. EMDataBank will continue to serve the 3DEM and
wider scientific communities with its 3DEM-specific portal for
deposition and access to EM-derived structures with links to
software, validation standards and conventions.
Summary information regarding the merger and detailed
specifications for data access will be posted at
EM Data Bank part of PDB Archive.

First contours of a vision for the future of validation at the PDB
The Worldwide Protein Data Bank (wwPDB; wwpdb.org) is pleased to direct PDB depositors and users to the recommendations of the wwPDB X-ray Validation Task Force (VTF) that were published in the journal Structure this week (2011, vol. 19: 1395-1412).
The wwPDB X-ray VTF was convened in 2008 to collect expert recommendations and develop consensus on validation methods that should be applied to crystal structures (models and data) in the PDB and to identify software applications to perform these validation tasks. These recommendations are the basis of a new validation suite that will be part of the new Common Tool for Deposition and Annotation (D&A) that is currently being developed by the wwPDB partners. The D&A tool and the X-ray validation pipeline will go into production by the end of 2012 at all wwPDB deposition sites (RCSB PDB, PDBe, PDBj and BMRB). From that moment in time on, depositors of X-ray crystal structures at the PDB will be provided with a detailed validation report. Such reports can be submitted to journals to accompany manuscripts describing new structures, and several publishers are working towards making such reports mandatory. Once the D&A tool is in production, the wwPDB partners also plan to provide the validation pipeline as a server, allowing crystallographers to assess their models before deposition and publication. Additional VTFs have been convened for NMR (by wwPDB) and 3DEM (by EMDataBank).
The wwPDB greatly appreciates the efforts of the authors of the X-ray VTF report: Randy J. Read, Paul D. Adams, W. Bryan Arendall III, Axel T. Brunger, Paul Emsley, Robbie P. Joosten, Gerard J. Kleywegt, Eugene B. Krissinel, Thomas Lütteke, Zbyszek Otwinowski, Anastassis Perrakis, Jane S. Richardson, William H. Sheffler, Janet L. Smith, Ian J. Tickle, Gert Vriend and Peter H. Zwart.

PDB Depositions Can Be Targets for CAPRI
Depositing a protein-protein, protein-DNA, protein-RNA or protein-peptide complex? Consider submitting your structure as a target for CAPRI after depositing your entry to the PDB.
CAPRI (Critical Assessment of PRedicted Interactions) is a community-wide, double-blind experiment aimed at assessing the performance of protein docking algorithms.
Submitting a target to CAPRI will help advance protein methods calculations, may provide new information on the quaternary structure of your complex, and should increase the visibility of your work. Moreover, CAPRI is designed to maintain strict target confidentiality, and imposes little delay on its publication.
More information about target submission is available at the CAPRI site and from the CAPRI management team (joel.janin@u-psud.fr).

PDB Archive Version 4.0 Released
As announced previously, the wwPDB has released PDB Archive Version 4.0. These files follow the PDB Exchange Dictionary v.4.0 and contain the results of remediating complex problems, including the representation of biological assemblies, residual B factors, peptide inhibitors and antibiotics, and entries in nonstandard crystal frames.
A description of the review and resulting changes and corrections is available in a PDF document and as a revision log that lists the changes made for each entry (XLS and CSV).
For PDB format files, only the entries changed during this remediation have been updated (<17000). These changes are identified as version 3.3 of the PDB file format. All files in PDBx/mmCIF and PDBML/XML formats reflect the new schema updates. Any changes made to the data are recorded in the PDBX_VERSION data category.
From July 13, 2011 onward, all new releases and modified entries will follow the updated formats (PDBx/PDBML v 4.0 and PDB File Format 3.3). Revisions to released entries will be tracked and numbered in the PDBx/mmCIF formatted files.
Users who maintain local copies of the wwPDB FTP can download the new files via rsync (see Download Archive - Data Download Instructions for more).
A time-stamped snapshot of the PDB archive before this release is available from ftp://snapshots.wwpdb.org/.

Time-stamped Copies of PDB Archive Available via FTP
A snapshot of the PDB archive (ftp.wwpdb.org) as of January 3, 2011 has been added to ftp://snapshots.wwpdb.org/. Snapshots have been archived annually since January 2005 to provide readily identifiable data sets for research on the PDB archive.
The directory 20110103 includes the 70,231 experimentally-determined coordinate files and related experimental data that were available at that time. Coordinate data are available in PDB, mmCIF, and XML formats. The date and time stamp of each file indicates the last time the file was modified.
The script at ftp://snapshots.wwpdb.org/rsyncSnapshots.sh may be used to make a local copy of a snapshot or sections of the snapshot.
