title: The stereochemical course of phosphoryl transfer catalyzed by herpes simplex virus type I-induced thymidine kinase.
abstract: Herpes simplex virus type I (HSV-I)-induced thymidine kinase has been shown to catalyze phosphoryl transfer from adenosine 5'-[gamma-(S)-16O,17O,18O]triphosphate to thymidine with inversion of configuration at phosphorus. The simplest interpretation of this result is that phosphoryl transfer occurs by a single in-line group transfer between ATP and thymidine within the ternary enzyme complex.
