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.

Future Planning: PDB entries with extended CCD or PDB IDs will be distributed in the PDBx/mmCIF format only

Future Planning: PDB entries with extended CCD or PDB IDs will be distributed in the PDBx/mmCIF format only

PDB users and related software developers should review code and begin to prepare for this change. Entries containing extended CCD or PDB IDs will not be distributed in legacy PDB file format.
