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.
10,000 NMR Structure Milestone Reached
The wwPDB is excited to announce that the number of structures available in the PDB archive determined using NMR spectroscopy has passed the 10,000 mark.
Small Angle Scattering Task Force
We are pleased to announce that the Report of the wwPDB Small-Angle Scattering Task Force, "Data Requirements for Biomolecular Modeling and the PDB Structure", has been published in the journal Structure (doi:10.1016/j.str.2013.04.020).
Landmark HIV Capsid Structures Released in PDB
Two complete HIV-capsid structures, both of unprecedented size, are described in this week's
issue of Nature and released in the Protein Data Bank (PDB; wwpdb.org). This represents a significant advance in the field of structural biology and a milestone for the PDB.
PDB entries 3J3Q and 3J3Y are models based on cryo-electron microscopy data and use of a molecular dynamics flexible-fitting method. They contain 1356 and 1176 protein chains, respectively, and over two million atoms each. The HIV-1 capsid is the protein envelope that encloses and protects the RNA genome of the virus. An important subject of study, the full capsid has been a difficult target for structural characterization due to its extremely large size and morphological variability.
