Abstract excerpt
All members of the herpesviridae contain within their large tegument protein a cysteine protease module that displays deubiquitinating activity. We report the crystal structure of the cysteine protease domain of murine cytomegalovirus M48 (M48(USP)) in a complex with a ubiquitin (Ub)-based suicide substrate. M48(USP) adopts a papain-like fold, with the active-site cysteine forming a thioether linkage to the...
