Mutational analysis of the hepatitis C virus (HCV) RNA-dependent RNA polymerase (RdRp) template channel identified two residues, Trp(397) and His(428), which are required for de novo initiation but not for extension from a primer. These two residues interact with the Delta1 loop on the surface of the RdRp. A deletion within the Delta1 loop also resulted in comparable activities. The mutant proteins exhibit increased double-stranded RNA binding compared with the wild type, suggesting that the Del ...[more]
