The Worldwide Protein Data Bank (wwPDB) consists of organizations that act as deposition, data processing
and distribution centers for PDB data.1
RCSB PDB (USA),
PDBe (Europe) and
and BMRB (USA).
The wwPDB's mission is to maintain a single PDB archive of macromolecular structural data
that is freely and publicly available to the global community.
Improved Representation of Large Structures in the PDB Archive
To meet the challenges of greater numbers of PDB depositions, involving ever larger and more complex structures, often determined using multiple methods, wwPDB has developed a new software system for structure deposition and annotation. This new system, currently in production for X-ray crystallographic entries, is based on the PDBx/mmCIF format and can thus handle structures of any size. Large structures have been processed and released intact by wwPDB since May 2013.
As announced previously, wwPDB has now combined the structures that were historically "split" across multiple entries into single PDBx/mmCIF files. Each combined file has been issued a new PDB identifier. This constitutes a significant improvement in the representation of large entries in the PDB archive.
The combined files will be made publicly available through the PDB archive on July 9, 2014.
