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.
Each site offers tools for searching, visualizing, and analyzing PDB data:
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.
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.
A snapshot of the PDB archive (ftp://ftp.wwpdb.org) as of January 2, 2015 has been added to ftp://snapshots.wwpdb.org/. Snapshots have been archived annually since January 2005 to provide readily identifiable data sets for research on the PDB archive.Read more
With this week's update, large structures (containing >62 chains and/or 99999 ATOM lines) represented as single files have been fully integrated into the main PDB FTP archive in both PDBx/mmCIF and PDBML formats, as announced in September. Previously, large structures were represented in multiple "SPLIT" entries, which have now been removed (obsoleted). Users searching for ID codes of "SPLIT" entries at wwPDB member websites will be automatically redirected to the combined entry.
A separate directory in the PDB FTP archive contains a TAR file including a collection of "best-effort," minimal, PDB format files for large structures that contain authorship, citation details and coordinate data, and an index file that contains the mapping between the chains present in the large entry and the chains present in the limited PDB-format files. DOIs for large structures will point to these TAR files.Read more
