The Biologically Interesting Molecule Reference Dictionary (BIRD) for Peptide-like Antibiotic and Inhibitor Molecules

The wwPDB's Biologically Interesting molecule Reference Dictionary (BIRD) describes antibiotics, peptide inhibitors, and other complex biological ligands.

To help define and represent these biologically interesting molecules, BIRD contains chemical descriptions, sequence and linkage information, and functional and classification information as taken from the core structures and from external resources.

All PDB entries containing these molecules have been annotated using this dictionary, with corresponding BIRD ID code contained only in the PDBx-formatted file. The use of BIRD will greatly improve the consistency of peptide-like antibiotic and inhibitor molecules in the PDB.

BIRD is available on the PDBj/wwPDB FTP server adjacent to the Chemical Component Dictionary at:

ftp://ftp.pdbj.org/pub/pdb/data/bird/prd/ (PDBj FTP site)

ftp://ftp.wwpdb.org/pub/pdb/data/bird/prd/ (wwPDB FTP site)

It is updated as new entries are added to the PDB archive. An overview of BIRD, along with definition details, is available from wwPDB web page.

News (on 6 Mar., 2013):
The latest version of jV, jV4.3, has been released. Please download the newest version from here. See Release note for more details.

News (on 16 Jan., 2013):
The new format, v.1.9.0, for the EMDB header file (XML file associated with each map) has been released.
All EMDB header files in the FTP archive have been updated to new version
(ftp://ftp.pdbj.org/pub/emdb/structures/EMD-∗∗∗∗/header/emd-∗∗∗∗.xml)

The EMDataBank deposition/annotation/search services will start using this new format.

The schema for 1.9.0 is available for download here:
ftp://ftp.pdbj.org/pub/emdb/doc/XML-schemas/Header-schema/current/emdb.xsd

A complete list of changes can be found at the beginning of the schema file. For more details about the schema change, see wwPDB News.

News (on 3 Jan., 2013):
The number of structures annotated by PDBj has reached 20,000.

PDBj has annotated 20,000 structures since we began annotating PDB entries in 2000. We are grateful to all depositors and wwPDB members for this great accomplishment.

"Statistics for PDB entries that are deposited and processed by year" is available on wwPDB Statistics page.

Remediation of Structure Factor Data and Release Plan

The wwPDB has reviewed structure factor files in the archive for format consistency and correspondence with coordinate data. As a result, around 43,800 structure factor files have been updated to standardize the format and to incorporate data corrections. Changes made are described in the audit.details record of the structure factor file.

Starting January 16, 2013, the wwPDB will begin to release these modified structure factors in weekly batches of 1000. These files will be available from ftp://ftp.pdbj.org/pub/pdb/data/structures/all/structure_factors/.

Questions should be sent to info@wwpdb.org.

News (on 21 Dec., 2012):
EMDB header format to be updated to v.1.9.0.

On 16 January 2013, the EMDB archive plans to adopt an updated format, v.1.9.0, for the entry header file (XML file associated with each map). This means that EMDB header files distributed from wwPDB partner sites will conform to the 1.9.0 format, and EMDataBank deposition/annotation/search services will start using this format.

We are announcing this planned change in advance so that developers can make any necessary modifications to software/services that make use of EMDB header files. Please contact us at help@emdatabank.org with any questions or concerns.

The candidate schema is available for download here:
ftp://ftp.pdbj.org/pub/emdb/doc/XML-schemas/Header-schema/candidate/emdb.xsd.
A complete list of changes can be found at the beginning of the schema file.

Example header files using the new format can be found here:

Validation Report PDFs

wwPDB members provide depositors with detailed reports that include the results of geometric and experimental data checking as part of the structure annotation process. These documents are available from all wwPDB annotation sites as PDF files so that they may be easily reviewed and shared by depositors.

As these PDB validation reports provide an assessment of structure quality while keeping the coordinate file confidential, we encourage journal editors and referees to request them from depositors as part of the manuscript submission and review process. The reports are date-stamped, and display the wwPDB processing site logo. They contain essentially the same information, regardless of PDB annotation site (Example reports: RCSB PDB | PDBe | PDBj). The validation reports will continue to be developed and improved as we receive recommendations from our Validation Task Forces for X-ray, NMR, EM, and small angle scattering methods, and as we further develop our data deposition and processing procedures.

PDB validation reports are already required by the International Union of Crystallography (IUCr) journals as part of their submission process and are described in an editorial recently published in Nature Structural & Molecular Biology.

Questions about these reports and the annotation process may be sent to PDBj or info@wwpdb.org.

Version 2 NMR Restraint Files to be Released in the wwPDB FTP on June 30, 2010

With the June 30, 2010 update, a new set of NMR restraint data files will be added to the wwPDB FTP archive (ftp://ftp.wwpdb.org, ftp://ftp.ebi.ac.uk, and ftp://pdb.protein.osaka-u.ac.jp). These restraint files, which will be identified as Version 2 files, are represented in NMR-STAR 3.1 format, contain current PDB atom nomenclature, and provide accurate atom-level correspondences to the NMR model coordinate files in the current wwPDB archive. Restraint files containing restraint data as originally deposited (Version 1 files) will remain on the site and will continue to be updated regularly as new NMR entries are released.

About Version 2 Restraint Files

The Version 2 NMR restraint files were generated for the wwPDB by the BMRB in collaboration with PDBe and the Centre for Molecular and Biomolecular Informatics/Institute for Molecules and Materials at the Radboud University Nijmegen.

NMR restraints were parsed from their original format (Version 1), and harmonized with the coordinates using the software packages Wattos (BMRB and CMBI/IMM), FormatConverter and NMRStarExport (PDBe), and the CCPN framework.

The complexity of this process may have lead to minor modifications or loss of data in the Version 2 restraint files due to parsing or conversion errors. The PDB coordinate file and the Version 1 restraint files remain the primary reference for these data.

More information about the process used to generate these files is available (1-3).

Changes to wwPDB FTP Server

The initial release of the Version 2 NMR restraint files will add approximately 5625 new files (310 Mbytes) to the wwPDB FTP site. Version 2 restraint files for new PDB entries will be processed and made available after the PDB entry has been released. Version 1 restraint files for new PDB entries will continue to be released weekly.

NMR restraint files are named using extension .mr, as in "1abc.mr.gz" for PDB ID 1abc. Version 2 restraint files will be named "1abc_mr.str.gz", where "str" identifies the NMR-STAR (V3.1) data format. All restraint files are compressed (.gz) using the GNU gzip program.

Version 2 restraint files will be stored in a new directory path, grouped by the middle two characters of the 4-character PDB ID:
ftp://pdb.protein.osaka-u.ac.jp/pub/pdb/data/structures/divided/nmr_restraints_v2/

All of these data files will be symbolically linked to a single directory:
ftp://pdb.protein.osaka-u.ac.jp/pub/pdb/data/structures/all/nmr_restraints_v2/

Version 1 restraint files will remain in their current directory structure.

For questions, please contact us or info@wwpdb.org.

Effective February 1, 2008, structure factor amplitudes/intensities (for crystal structures) and restraints (for NMR structures) will be a mandatory requirement for PDB deposition.

These data must be deposited at a member site of the Worldwide Protein Data Bank (www.wwpdb.org): PDBj (www.pdbj.org), RCSB PDB (www.pdb.org), PDBe (www.ebi.ac.uk/msd), or BMRB (www.bmrb.wisc.edu).

Data can be released as soon as they have been processed and approved. There is a one-year limit on the length of time a structure and its experimental data can be put on hold, including structures that are on hold until the associated paper is published (HPUB).

This policy was developed as a result of comments and recommendations from the PDB user community, including the Commission on Biological Macromolecules of the International Union of Crystallography and the NMR Task Force, and has been endorsed by the wwPDB Advisory Committee.
