| + | == Publication Abstract from PubMed == | ||
| + | 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. | ||
