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.

Celebrating 50 Years of the PDB


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.
