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.
Simple and advanced searching for macromolecules and ligands, tabular reports, specialized visualization tools, sequence-structure comparisons, 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.
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.
wwPDB validation of EM structures for which there is both a model and an EM volume will include the Q-score metric
PDB users and related software developers should review code and begin to prepare for this change. Entries containing extended CCD or PDB IDs will not be distributed in legacy PDB file format.
Programmatic users (ftp, rsync or https) should update scripts as soon as possible.
