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.


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.


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.

News & Announcements

May 25, 2016

Effective May 25, 2016, new deposition sessions will be directed to the wwPDB partner site designated for processing: Europe and Africa→PDBe/UK; Asia and the Middle East→PDBj/Japan; and Americas, Australia, and Oceania→RCSB PDB/US. This new arrangement will help to ensure faster response times for communications and balanced distribution of the data curation load among the wwPDB partner sites.

PDB depositors can help the structure modeling community test prediction methods by making protein sequences available while the structure is on hold. To designate your structure as a CASP target, use the Release Status page during deposition.  Ideal candidates would have a sequence identity to available structures below 50% or are otherwise interesting for prediction.
