GHMP kinase family

In molecular biology, the GHMP kinase family is a family of kinase enzymes. Members of this family include homoserine kinases EC 2.7.1.39, galactokinases EC 2.7.1.6, and mevalonate kinasesEC 2.7.1.36. These kinases make up the GHMP kinase superfamily of ATP-dependent enzymes.[1] These enzymes are involved in the biosynthesis of isoprenes and amino acids as well as in carbohydrate metabolism. These enzymes contain, in their N-terminal section, a conserved Gly/Ser-rich region which is probably involved in the binding of ATP.[2][3] The C-terminal domain of homoserine kinase has a central alpha-beta plait fold and an insertion of four helices, which, together with the N-terminal fold, creates a novel nucleotide binding fold.[4]
