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
wwPDB data centers serve as deposition, annotation, and distribution sites of the PDB archive. Each site offers tools for searching, visualizing, and analyzing PDB data.
Simple and advanced searching for macromolecules and ligands, tabular reports, specialized visualization tools, sequence-structure comparisons, RCSB PDB Mobile, Molecule of the Month and other educational resources at PDB-101, 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.
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.
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.
The latest 2016 snapshot of the PDB FTP archive includes 125,463 experimentally-determined coordinate files and related experimental data available at that time. The snapshot is 757 GB.
The wwPDB and the EMDataBank/Unified Data Resource for 3DEM Project have collaborated to update the experimental methods descriptions of all electron microscopy and electron crystallography-derived structures in the PDB archive.
The wwPDB and the EMDataBank/Unified Data Resource for 3DEM Project (https://www.ncbi.nlm.nih.gov/pubmed/26578576) are collaborating to update the experimental methods descriptions of all electron microscopy and electron crystallography-derived structures in the PDB archive. When completed, all 3DEM-derived entries will have better organized content and will conform to the revised data model developed by the EMDataBank team for use within the wwPDB OneDep System.
