CC -!- FUNCTION: Catalyzes the transfer of the gamma-phospho group of ATP to
CC thymidine to generate dTMP in the salvage pathway of pyrimidine
CC synthesis. The dTMP serves as a substrate for DNA polymerase during
CC viral DNA replication. Allows the virus to be reactivated and to grow
CC in non-proliferative cells lacking a high concentration of
CC phosphorylated nucleic acid precursors. {ECO:0000255|HAMAP-
CC Rule:MF_04029}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + thymidine = ADP + dTMP + H(+); Xref=Rhea:RHEA:19129,
CC ChEBI:CHEBI:15378, ChEBI:CHEBI:17748, ChEBI:CHEBI:30616,
CC ChEBI:CHEBI:63528, ChEBI:CHEBI:456216; EC=2.7.1.21;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_04029};
CC -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_04029}.
CC -!- SIMILARITY: Belongs to the herpesviridae thymidine kinase family.
CC {ECO:0000255|HAMAP-Rule:MF_04029}.
