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
Explore Integrative Structures at RCSB.org
Access complex macromolecular assemblies modeled using integrative methods together with other experimental structures and Computed Structure Models using your favorite RCSB PDB tools

Announcement: Ligand Expo To Be Retired in 2025
Users should transition to RCSB PDB and wwPDB services as soon as possible
Watch the Webinar: Seeing Bird Flu in 3D
This virtual course will help you explore Influenza A H5N1 virus protein structures using RCSB.org tools
Watch the Webinar: Streamlining Access to RCSB PDB APIs with Python
This virtual course introduces and demonstrates usage of the rcsb-api Python package for easy interactions with RCSB PDB Search and Data API services
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.
Sequence Annotations Viewer: Geometry Validation
Map validation scores and geometry validation metrics onto sequence annotations and 3D structure
Register Now for Crash Course: Python For Cheminformatics-Driven Molecular Docking
This free virtual course will demonstrate the power and flexibility of python on May 1, 2025
