HYDROLYTIC ENZYME HUMAN CYTOMEGALOVIRUS PROTEASE
Overview
Human cytomegalovirus (hCMV), a herpesvirus, infects up to 70% of the, general population in the United States and can cause morbidity and, mortality in immunosuppressed individuals (organ-transplant recipients and, AIDS patients) and congenitally infected newborns. hCMV protease is, essential for the production of mature infectious virions, as it performs, proteolytic processing near the carboxy terminus (M-site) of the viral, assembly protein precursor. hCMV protease is a serine protease, although, it has little homology to other clans of serine proteases. Here we report, the crystal structure of hCMV protease at 2.0 angstroms resolution, and, show that it possesses a new polypeptide backbone fold. Ser 132 and His 63, are found in close proximity in the active site, confirming earlier, biochemical and mutagenesis studies. The structure suggests that the third, member of the triad is probably His 157. A dimer of the protease with an, extensive interface is found in the crystal structure. This structure, information will help in the design and optimization of inhibitors against, herpesvirus proteases.
