All of the released PDB entries are now available in XML format from the PDB beta FTP site at
are welcomed on these data.
The XML data files have been created by software translation of
the mmCIF data files
created as part of the PDB Data Uniformity Project. The mmCIF
data files use the data items defined in the PDB Exchange
Dictionary(deposit.pdb.org/mmcif). The XML data files conform to an
XSD style XML Schema
derived from the PDB Exchange Dictionary. As a result, the element and
attribute names in the XML data files directly correspond to the item
names defined the PDB Exchange Dictionary.
The delivery of PDB data in XML format is the product of a
collaboration between the Protein Data Bank Japan (PDBj),
the Macromolecular Structure Database (MSD) group at
European Bioinformatics Institute (EBI), and the Research
Collaboratory for Structural Bioinformatics (RCSB).
The RCSB PDB (citation) is managed by two members of the Research Collaboratory for Structural Bioinformatics:
