HERPES SIMPLEX VIRUS TYPE II PROTEASE
|
OverviewOverview
Human herpes simplex virus type 1 (HSV-1) and type 2 (HSV-2) are, responsible for herpes labialis (cold sores) and genital herpes, respectively. They encode a serine protease that is required for viral, replication, and represent a viable target for therapeutic intervention., Here, we report the crystal structures of HSV-1 and HSV-2 proteases, the, latter in the presence and absence of the covalently bound transition, state analog inhibitor diisopropyl phosphate (DIP). The HSV-1 and HSV-2, protease structures show a fold that is neither like chymotrypsin nor like, subtilisin, and has been seen only in the recently determined, cytomegalovirus (CMV) and varicella-zoster virus (VZV) protease, structures. HSV-1 and HSV-2 proteases share high sequence homology and, have almost identical ... [(full description)]
