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: ACT domain

This entry represents a motif conserved in many allosteric enzymes involved in amino acid and purine biosynthesis, called the ACT domain as the acronym for aspartate kinase, chorismate mutase, and TyrA (prephenate dehydrogenase). Several crystal structures have been determined for proteins that have ACT domains, such as 3-phosphoglycerate dehydrogenase (3PGDH),15 threonine deaminase (TD),16 acetohydroxyacid synthase III,17 and NikR, a transcriptional regulator involved in nickel uptake. The ACT domain consists of 4 beta-strands and 2 alpha-helices PMID:17350037.
