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
1QHI is a Single protein structure of sequence from Human herpesvirus 4 with and as ligands. Active as Thymidine kinase, with EC number 2.7.1.21 Full crystallographic information is available from OCA.
