This family catalyses the phosphorylation of the 3'-hydroxyl group of dephosphocoenzyme A to form Coenzyme A EC:2.7.1.24. This enzyme uses ATP in its reaction.
This family has been suggested to belong to the nucleotidyltransferase superfamily [1]. It occurs at the C-terminus of dephospho-CoA kinase (CoaE) in a number of cases, where it plays a role in the proper folding of the enzyme [2].
