Molecular Function Browser

Searches or browses for structure by Gene Ontology Molecular Function terms. Molecular Function terms are a set of controlled vocabulary terms defined by the Gene Ontology project (

The Molecular Function Browser permits the user to navigate through the Molecular Function hierarchy to arrive at the subset of particular interest. The browser opens up the top level in the hierarchy. Clicking on the arrow/folder icons expands the respective nodes. Clicking on the name of the node will retrieve all PDB IDs assigned to that node.
