'''STRUCTURE OF A TYPE II THYMIDINE KINASE WITH BOUND DTTP'''<br />


==Overview==
==Structure of a type II thymidine kinase with bound dTTP==
The structure of human cytosolic thymidine kinase in complex with its, feedback inhibitor 2'-deoxythymidine-5'-triphosphate was determined. This, structure is the first representative of the type II thymidine kinases, found in several pathogens. The structure deviates strongly from the known, structures of type I thymidine kinases such as the Herpes simplex enzyme., It contains a zinc-binding domain with four cysteines complexing a, structural zinc ion. Interestingly, the backbone atoms of the type II, enzyme bind thymine via hydrogen-bonds, in contrast to type I, where side, chains are involved. This results in a specificity difference exploited, for antiviral therapy. The presented structure will foster the development, of new drugs and prodrugs for numerous therapeutic applications.
