EC 2.7.4.25     
Accepted name: (d)CMP kinase
Reaction: ATP + (d)CMP = ADP + (d)CDP
Glossary: CMP = cytidine monophosphate
dCMP = deoxycytidine monophosphate
CDP = cytidine diphosphate
dCDP = deoxycytidine diphosphate
UMP = uridine monophosphate
UDP = uridine diphosphate
Other name(s): prokaryotic cytidylate kinase; deoxycytidylate kinase; dCMP kinase; deoxycytidine monophosphokinase
Systematic name: ATP:(d)CMP phosphotransferase
Comments: The prokaryotic cytidine monophosphate kinase specifically phosphorylates CMP (or dCMP), using ATP as the preferred phosphoryl donor. Unlike EC 2.7.4.14, a eukaryotic enzyme that phosphorylates UMP and CMP with similar efficiency, the prokaryotic enzyme phosphorylates UMP with very low rates, and this function is catalysed in prokaryotes by EC 2.7.4.22, UMP kinase. The enzyme phosphorylates dCMP nearly as well as it does CMP [1].
