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: DhaL domain

This entry represents the DhaL domain which consists of eight antiparallel alpha-helices arranged in an up-and-down geometry and aligned on a circle. This results in the formation of a helix barrel enclosing a deep pocket. The helices are amphipathic with the hydrophobic side chains directed into the pocket of the barrel and with the polar residues exposed. The nucleotide is bound on the top of the barrel PMID:16647083,PMID:12966101.

The DhaL alpha helix barrel fold appears not only as a C-terminal domain in Dha kinases but also as an N-terminal domain in a family of two-domain proteins with unknown function. One representative example is YfhG of Lactococcus lactis PMID:12966101.
