SYSTEMATIC NAME
IUBMB Comments
ATP:thymidine 5'-phosphotransferase
Deoxyuridine can also act as acceptor, and dGTP can act as a donor. The deoxypyrimidine kinase complex induced by Herpes simplex virus catalyses this reaction as well as those of EC 2.7.1.114 (AMP---thymidine kinase), EC 2.7.1.118 (ADP---thymidine kinase) and EC 2.7.4.9 (dTMP-kinase).
