Since 1971, the Protein Data Bank archive (PDB) has served as the single repository of information about the 3D structures of proteins, nucleic acids, and complex assemblies.

The Worldwide PDB (wwPDB) organization manages the PDB archive and ensures that the PDB is freely and publicly available to the global community.

wwPDB Members

wwPDB data centers serve as deposition, annotation, and distribution sites of the PDB archive. Each site offers tools for searching, visualizing, and analyzing PDB data.

PDBe

Rich information about all PDB entries, multiple search and browse facilities, advanced services including PDBePISA, PDBeFold and PDBeMotif, advanced visualisation and validation of NMR and EM structures, tools for bioinformaticians.

RCSB PDB

Simple and advanced searching for macromolecules and ligands, tabular reports, specialized visualization tools, sequence-structure comparisons, RCSB PDB Mobile, Molecule of the Month and other educational resources at PDB-101, and more.

PDBj

Supports browsing in multiple languages such as Japanese, Chinese, and Korean; SeSAW identifies functionally or evolutionarily conserved motifs by locating and annotating sequence and structural similarities, tools for bioinformaticians, and more.

BMRB

Collects NMR data from any experiment and captures assigned chemical shifts, coupling constants, and peak lists for a variety of macromolecules; contains derived annotations such as hydrogen exchange rates, pKa values, and relaxation parameters.

News & Announcements

June 24, 2016

To enable better annotation and tracking, the wwPDB partners encourage depositors to provide ORCID identifiers and information on relevant grants funding their research when depositing PDB data.

ORCID identifiers are unique to each researcher; usage will help avoid ambiguity in attributing the correct authorship of PDB, BMRB, and EMDB entries. In order to register an ORCID, please visit http://orcid.org.

Starting June 30, users looking for the wwPDB website can use either wwPDB.org or PDB.org as the URL. RCSB PDB resources will continue to be hosted at RCSB.org. No changes need to be made to bookmarked RCSB PDB resources.

In January 2014, the wwPDB launched a unified deposition, annotation, and validation system (RCSB PDB | PDBe | PDBj) for structures determined using X-ray crystallography. More than 14000 structures have been deposited, annotated, and validated using this system, with more than 9000 structures already released into the PDB archive. The new system uses the PDBx/mmCIF data format, which produces more uniform data, supports replacement of data files pre- and post-deposition, enhances communication with depositors, enables improved annotation, and provides validation reports based on recommendations from wwPDB expert task forces. Improvements to this system are regularly incorporated in response to user feedback. Detailed information and video tutorials are available.
