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.

Features & Highlights
wwPDB Validation Reports Accessible via API
Programmatically retrieve wwPDB validation reports data alongside structural model annotations
Download Snapshots of the PDB Core Archive via HTTPS, SYNC, RSYNC, or FTP
Snapshots from RCSB PDB and PDBj provide readily identifiable data sets for research on the PDB archive. At RCSB PDB, AWS SYNC has replaced RSYNC.
Introducing Extended PDB IDs at RCSB.org
Search, view, and download all PDB structures using their extended PDB ID.
wwPDB anticipates that all four-character PDB IDs will be exhausted by 2028, after which only 12-character PDB IDs will be issued.
