Welcome

RCSB Protein Data Bank (RCSB PDB) enables breakthroughs in science and education by providing access and tools for exploration, visualization, and analysis of:

Experimentally-determined 3D structures from the Protein Data Bank (PDB) archive

Computed Structure Models (CSM) from AlphaFold DB and ModelArchive

These data can be explored in context of external annotations providing a structural view of biology.

Register for June 13 Virtual Office Hour: Generating DSN6 and MTZ Files

DSN6 formatted map files will not be offered after June 28, 2024. MTZ files available from EDMAPS.rcsb.org will be discontinued in the Fall. Join us for a Virtual Office Hour to learn more about this transition, and how you can generate the data you need.

Notice: NGL Viewer Deprecation

Notice: NGL Viewer Deprecation

As of June 28, 2024, the NGL molecular viewer will be removed from RCSB.org. Users are encouraged to use Mol* for 3D visualization.

Switch from MMTF to BCIF

Switch from MMTF to BCIF

As of July 2, 2024, RCSB PDB will no longer serve PDB data in the MMTF compression format. Users should switch to BCIF.

Register Now for a Webinar on Understanding PDB Validation: Which experimental structures should I rely on?

Join us on May 14 to learn about primary PDB structure quality metrics, including those in the validation slider graphic; how PDB structure quality varies across the archive; and identify good structure(s) for research from RCSB.org

Coming soon: Annotation of Protein Modifications in the PDB

Coming soon: Annotation of Protein Modifications in the PDB

By the end of 2024, wwPDB will roll out updated atomic coordinate files as well as updated CCD files containing additional annotation describing protein chemical modifications (PCMs) and post translational modifications (PTMs)
