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.

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.


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.


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, tabular reports, specialized visualization tools, sequence-structure comparisons, RCSB PDB Mobile, Molecule of the Month and other educational resources at PDB-101, and more.

wwPDB will introduce a file versioning system to retain depositor-initiated updates of previously released coordinate entries. A new FTP repository will host versioned files.

The model files in the PDB FTP archive have been updated to V5.0 of the PDBx/mmCIF dictionary. Both mmCIF and XML formats have been updated. These files were provided previously for the community to review and test. There is no change to PDB format files as PDB format is a legacy format. These, therefore, do not contain all of the remediated information.
