IntEnz Enzyme Nomenclature


Accepted name:
deoxycytidine kinase
Other names:
2'-deoxycytidine kinase
Ara-C kinase
arabinofuranosylcytosine kinase
deoxycytidine kinase (phosphorylating)
deoxycytidine-cytidine kinase
Systematic name:
NTP:deoxycytidine 5'-phosphotransferase



Cytosine arabinoside can act as acceptor; all natural nucleoside triphosphates (except dCTP) can act as donors.
