***wwPDB Announcement: Release of Remediated PDB Data***
The wwPDB has collaborated on a project to remediate the PDB archive
and create a new set of corrected files.
The entire archive has been reviewed and remediated with the
objectives of improving the detailed chemical description of non-
polymer and monomer chemical components; standardizing atom
nomenclature; updating sequence database references and taxonomies;
resolving any remaining differences between chemical and
macromolecular sequences; improving the representation of viruses;
and verifying primary citation assignments. In addition, the atom
nomenclature for amino acids and nucleotides now conforms with IUPAC
A new FTP server containing the remediated data has been set up for
testing. The access details for this site are provided at http://
http://www.wwpdb.org/remediation-downloads.html. The new ftp site will be
updated weekly in concert with the current production site at ftp://
ftp.rcsb.org. Both sites share the same directory structure. Starting
May 1, the remediated data will be served using gzip compression.
Your input is very important to us. PDB users are encouraged to test
the remediated data files between now and July 2007. The details of
the final transition will be announced on the wwPDB website (http://
