Enzyme Information

2.7.4.25
(d)CMP kinase.
based on mapping to UniProt Q5SL35
ATP + (d)CMP = ADP + (d)CDP.
-!- 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 catalyzed in prokaryotes by EC 2.7.4.22. -!- The enzyme phosphorylates dCMP nearly as well as it does CMP.
