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.

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.
Undergrads: Spend your summer with RCSB PDB
RISE at Rutgers is a nationally acclaimed summer research program for outstanding undergraduates from diverse backgrounds. Applications are now open.
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.
Resources for Supporting the Extended PDB ID Format (pdb_00001abc)
Users and related software will need to transition to the extended PDB ID format and PDBx/mmCIF file format by 2029
Applications Open for Director
Distinguished scientists focused on 3D structures of biological macromolecules are invited to apply for this position with the RCSB PDB at Rutgers University.
Time-stamped Copies of PDB and EMDB Archives
Snapshots of the PDB and EMDB Core archives as of January 2024 are available.
Improved Depositor Experience Using ORCiD
ORCiD summary table improvements include expanded details and a sorting function
PDB Entries with Novel Ligands Now Distributed Only in PDBx/mmCIF and PDBML File Formats
PDB has run out of 3-character CCD IDs. Entries with novel ligands will not be distributed in the legacy PDB file format
