The protease domain of the hepatitis C virus (HCV) protein NS3 was expressed in Escherichia coli, purified to homogeneity, and shown to be active on peptides derived from the sequence of the NS4A-NS4B junction. Experiments were carried out to optimize protease activity. Buffer requirements included the presence of detergent, glycerol, and dithiothreitol, pH between 7.5 and 8.5, and low ionic strength. C- and N-terminal deletion experiments defined a peptide spanning from the P6 to the P4… CONTINUE READING
