Ligand Expo
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.
Getting Started:
- The Ligand Expo Tutorial contains a summary of query, report and download features.
- Select the Search menu to find a chemical component or build a new chemical component.
- Select the Browse menu to view tabulations of modified amino acids and nucleotides.
- Select the Download for links to chemical dictionaries and resource files.
- Go here for a brief tutorial on the content of the Chemical Component Dictionary.
