PDBsum

PDBsum is database that provides an overview of the contents of each 3D macromolecular structure deposited in the Protein Data Bank.

Each structure in the PDBsum database includes an image of structure, molecular components contained in the complex, enzyme reaction diagram if appropriate, Gene Ontology functional assignments, a 1D sequence annotated by Pfam and InterPro domain assignments, description of bound molecules and graphic showing interactions between protein and secondary structure, schematic diagrams of protein-protein interactions, analysis of clefts contained within the structure and links to external databases.
