HERPES SIMPLEX VIRUS TYPE-I THYMIDINE KINASE COMPLEXED WITH A NOVEL NON-SUBSTRATE INHIBITOR, 9-(4-HYDROXYBUTYL)-N2-PHENYLGUANINE

Overview

Treatment of herpes infections with nucleoside analogues requires as an, initial step the activation of the compounds by thymidine kinase. As an, aid to developing more effective chemotherapy, both for treatment of, recurrent herpes infection and in gene therapy systems where thymidine, kinase is expressed, two high-resolution X-ray structures of thymidine, kinase have been compared: one with the relatively poor substrate, aciclovir (Zovirax), the other with a synthetic inhibitor having an, N2-substituted guanine. Both compounds have similar binding modes in spite, of their size difference and apparently distinct ligand properties.

About this Structure
