(d)CMP kinase

(d)CMP kinase (EC 2.7.4.25, prokaryotic cytidylate kinase, deoxycytidylate kinase, dCMP kinase, deoxycytidine monophosphokinase) is an enzyme with systematic name ATP:(d)CMP phosphotransferase.^[1]^[2] This enzyme catalyses the following chemical reaction

ATP + (d)CMP

\rightleftharpoons

ADP + (d)CDP

The prokaryotic cytidine monophosphate kinase specifically phosphorylates CMP (or dCMP).
