GeezerVison is showing www.wwpdb.org — wwPDB: Worldwide Protein Data Bank

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.

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
Protein Data Bank China

Protein Data Bank China (PDBc) has joined Worldwide Protein Data Bank (wwPDB) as an Associate Member in 2022. PDBc is based in the National Facility for Protein Science in Shanghai which is associated with the Shanghai Advanced Research Institute of Chinese Academy of Sciences, the Shanghai Institute for Advanced Immunochemical Studies and the iHuman Institute of ShanghaiTech University.

Research Collaboratory for Structural Bioinformatics Protein Data Bank

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.

Biological Magnetic Resonance Data Bank

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.

Electron Microscopy Data Bank

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.

Protein Data Bank in Europe

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.

Protein Data Bank Japan

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).
