[https://www.uniprot.org/uniprot/KITH_EHV4 KITH_EHV4] In latent infection, may allow the virus to be reactivated and to grow in cells lacking a high concentration of phosphorylated nucleic acid precursors, such as nerve cells that do not replicate their genome (By similarity).

== Publication Abstract from PubMed ==
 +
Crystal structures of equine herpesvirus type-4 thymidine kinase (EHV4-TK) in complex with (i). thymidine and ADP, (ii). thymidine and SO(4) and the bisubstrate analogs, (iii). TP(4)A, and (iv). TP(5)A have been solved. Additionally, the structure of herpes simplex virus type-1 thymidine kinase (HSV1-TK) in complex with TP(5)A has been determined. These are the first structures of nucleoside kinases revealing conformational transitions upon binding of bisubstrate analogs. The structural basis for the dual thymidine and thymidylate kinase activity of these TKs is elucidated. While the active sites of HSV1-TK and EHV4-TK resemble one another, notable differences are observed in the Lid regions and in the way the enzymes bind the base of the phosphoryl-acceptor. The latter difference could partly explain the higher activity of EHV4-TK toward the prodrug ganciclovir.
