CATH Release v3.3
CATH Release v3.3

The latest version of CATH (v3.3) has now been officially released and available at www.cathdb.info. This release includes 226 new superfamilies (total 2,593), 1,148 sequence families (total 10,019) and 14,473 newly classified protein domains.


The release was actually fixed a while ago, but it has taken us a few months to generate all the extra data and extra features that the site now contains. These extra features include:

  • Structural clusters and alignments
  • Structural comparisons
  • Functional annotations
  • Greatly improved search facilities
  • More intuitive interface (hopefully)

More information on the release can be found on the links below. Please do let us know if you have any comments, suggestions, requests by sending an email to cathteam@biochem.ucl.ac.uk.
