Functional Families

Overview of the Structural Clusters (SC) and Functional Families within this CATH Superfamily. Clusters with a representative structure are represented by a filled circle.

Superfamily: Host-nuclease inhibitor protein Gam

This superfamily consists of 4 alpha helices, 2 long and 2 short.

Within bacteriophage lambda protein Gam, one of the long helices (H4) acts as a dimerisation interface to form an antiparallel helix. The two short helices (H2 and H3) from each dimer form a 'cross-brace', while the other long helix (H1) protrudes out of the protein. Within bacteriophage lambda, Gam is involved in inhibiting host nucleases.
