Enzyme Information

2.7.1.21
Thymidine kinase.
based on mapping to UniProt P03176
ATP + thymidine = ADP + thymidine 5'-phosphate.
-!- Deoxyuridine can also act as acceptor. -!- dGTP can also act as donor. -!- The deoxypyrimidine kinase complex induced by Herpes simplex virus catalyzes this reaction as well as those of EC 2.7.1.114, EC 2.7.1.118 and EC 2.7.4.9. -!- Formerly EC 2.7.1.75.
