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 PDB Data Distributions
Many statistics are available, including PDB holdings by experimental method and molecular type, along with numbers for structures with experimental and small molecule data
Toggle to "Opt-in" to Access Computed Structure Models Alongside PDB Data
Move the slider to use RCSB PDB tools with >1 million CSMs from AlphaFold and ModelArchive
Guide to Understanding PDB Data: Intro to APIs
PDB-101's Guide helps non-experts navigate through the PDB. A new chapter introduces the APIs that query and deliver PDB data at RCSB.org.
Search for Structures or Feature Help, News, and PDB-101
Use the pulldown menu to target queries of 3D structures (PDB structures and Computed Structure Models) or Documentation (User Guides, News Announcements, and PDB-101 Features)
