Specificity Catalyses the reaction: ATP + (d)CMP = ADP + (d)CDP. The prokaryotic cytidine monophosphate kinase specifically phosphorylates CMP (or dCMP), using ATP as the preferred phosphoryl donor.
Specific Activity ~ 15 U/mg (25°C, pH 7.6 on CMP)
Storage Conditions

Storage Temperature: 2-8°C

Stability: Minimum 1 year at 4°C. Check vial for details.

Synonyms (d)CMP kinase; ATP:CMP phosphotransferase; UMP-CMP kinase
Temperature Optima (°C) 25
Unit Definition One Unit of cytidylate kinase is defined as the amount of enzyme required to produce one μmole of CDP from CMP and ATP per minute, in the presence of NADH, in TEA buffer (73 mM), pH 7.6 at 25°C.
