CATH Classification Browser (opens popup)
Searches or browses for structures by CATH terms (Class, Architecture, Topology, and Homologous superfamily). CATH is a semi-automatic hierarchical classification of protein domains (http://www.cathdb.info/).
The CATH Browser permits the user to navigate through the CATH 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.
Important: Make sure pop-ups are enabled in your browser (Click here to check).
