Message from the PDB

This past summer, the PDB attended several meetings and discussed with users several of the new features available. One of these developments is the release of of files and images of the biologically active units for all structures in the archive. Another is the release of standalone software for the preparation, validation, and deposition of macromolecular data.

  • The PDB has provided separate coordinate and image files containing the biological molecule. These can be accessed from the Structure Explorer "View Structure" and "Download/Display File" pages.

  • Software is available for download and installation on your desktop from Software binaries are provided as compressed files; README files are included with installation instructions. Some of the programs available include: PDB_EXTRACT, which extracts mmCIF data from structure determination applications; ADIT, which prepares files that can be emailed to the PDB for deposition; and the PDB Validation Suite, which processes and checks structure data.

We welcome your comments and questions about these features at
