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.

Celebrating 50 Years of the PDB

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

Celebrating 20 Years of the wwPDB Partnership

Vision and Mission

Vision

Sustain freely accessible, interoperating Core Archives of structure data and metadata for biological macromolecules as an enduring public good to promote basic and applied research and education across the sciences.

Mission

  • Manage the wwPDB Core Archives as a public good according to the FAIR Principles.
  • Provide expert deposition, validation, biocuration, and remediation services at no charge to Data Depositors worldwide.
  • Ensure universal open access to public domain structural biology data with no limitations on usage.
  • Develop and promote community-endorsed data standards for archiving and exchange of global structural biology data.
wwPDB Members

Multilingual access (English, Japanese, Chinese, and Korean) and comprehensive structural tools, including advanced querying (PDBj Mine), shape similarity search (Omokage), and visualization (Molmil). Maintains unique archives for computational models (BSM-Arc) and raw diffraction data (XRDa).

Collects 3D volumes & associated information of macromolecular complexes & subcellular structures from electron cryo microscopy & electron cryo tomography; develops resources for searching, data mining, analyzing, validating & visualizing data.

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.

Simple and advanced searching for macromolecules and ligands, flexible APIs for programmatic users, specialized 1D-3D visualization tools, Molecule of the Month and other training 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.
