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.

All Deposition Resources
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.
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.
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.
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.
This enriched PDB archive provides annotation from external database resources in the metadata in addition to content provided in structure model files
A new PDBx/mmCIF category will improve information collected about starting models for X-ray, 3DEM and NMR methods
ModelCIF is an extension of PDBx/mmCIF data representation
