Reaction: ATP + cytidine = ADP + CMP
Systematic name: ATP:cytidine 5'-phosphotransferase
Comments: The enzyme, characterized from the archaeon Thermococcus kodakarensis, participates in a pathway for nucleoside degradation. The enzyme can also act on deoxycytidine and uridine, but unlike EC 220.127.116.11, uridine kinase, it is most active with cytidine.
