Description
(d)CMP kinase (EC 2.7.4.25, prokaryotic cytidylate kinase, deoxycytidylate kinase, dCMP kinase, deoxycytidine monophosphokinase) is an enzyme with system name ATP:(d)CMP phosphotransferase. This enzyme catalyses the following chemical reaction: ATP + (d)CMP ↔ ADP + (d)CDP. The prokaryotic cytidine monophosphate kinase specifically phosphorylates CMP (or dCMP).
