Thus, the two substrates of this enzyme are ATP and dCMP, whereas its two products are ADP and dCDP.

This enzyme belongs to the family of transferases, specifically those transferring phosphorus-containing groups (phosphotransferases) with a phosphate group as acceptor. The systematic name of this enzyme class is ATP:CMP phosphotransferase. Other names in common use include: deoxycytidylate kinase, deoxycytidylate kinase, CMP kinase, CTP:CMP phosphotransferase, dCMP kinase, deoxycytidine monophosphokinase, UMP-CMP kinase, ATP:UMP-CMP phosphotransferase, and pyrimidine nucleoside monophosphate kinase. This enzyme participates in pyrimidine metabolism.
