PG - 4136-41 AB - After the U53 gene encoding the proteinase from human herpesvirus 6 (HHV-6) was sequenced, it was expressed in Escherichia coli, and the activity of the purified, recombinant HHV-6 proteinase was characterized quantitatively by using synthetic peptide substrates mimicking the release and maturation cleavage sites in the polyprotein precursors of HHV-6, human cytomegalovirus (CMV), murine CMV, and Epstein-Barr virus. Despite sharing 40% identity with other betaherpesvirus proteinases such as human CMV proteinase, the one-chain HHV-6 enzyme was distinguished from these two-chain proteinases by the absence of an internal autocatalytic cleavage site.
