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.

Vision and Mission


Sustain a freely accessible, single global archive of experimentally determined structure data for biological macromolecules as an enduring public good.


  • Ensure open access to public domain experimentally determined structural biology data.
  • Provide expert deposition, validation, and biocuration services at no charge to Data Depositors.
  • Enable universal access for expert and non-expert Data Consumers with no limitations on usage.
  • Manage the PDB archive as a public good according to the FAIR Principles.
  • Lead the world in structural biology data representation, exchange, and visualization.
wwPDB Members

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.

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.

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.

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.

News & Announcements


The wwPDB OneDep system for deposition, validation and biocuration will require contact authors to provide their unique ORCiD identifiers when preparing depositions later this summer. This change will enable wwPDB efforts to correctly attribute PDB structures to contact authors. At a later point, ORCiD will be used to authenticate and reorganize access to deposition data within OneDep.

The new version of OneDep improves the process of data replacement for PDB and EMDB entries, prior to their release.

The Office of Research Integrity (ORI) of the U.S. Department of Health and Human Services has announced their final Research Misconduct Finding in the case of H.M. Krishna Murthy. The Administrative Law Judge found that Murthy reported falsified and/or fabricated research in 10 journal publications and 12 corresponding PDB structures. Per wwPDB policies, all 12 PDB structures in question have been obsoleted. The Judge’s finding was the result of years of work on the part of the dedicated ORI legal team, who were assisted by members of the US regional data centre of the wwPDB and expert structural biologists. Mandatory PDB deposition of both atomic coordinates and experimental data were critical to resolving this case.
