Ligand Expo

Ligand Expo will be down from January 1-31, 2023. Requests to this service will return a 410 http error code (“Gone”) and a message to contact RCSB PDB. Please help us better understand which Ligand Expo features are utilized and should be integrated with by taking this survey.

Ligand Expo (formerly Ligand Depot) provides chemical and structural information about small molecules within the structure entries of the Protein Data Bank. Tools are provided to search the PDB dictionary for chemical components, to identify structure entries containing particular small molecules, and to download the 3D structures of the small molecule components in the PDB entry. A sketch tool is also provided for building new chemical definitions from reported PDB chemical components. The data in Ligand Expo are updated weekly.
