    摘要： This invention provides efficient HCV replicase complexes comprising novel RNA template and primer pair. Assay systems are also provided, which use such complexes, for detecting replicase activity, quantitatively studying the kinetics and mechanism of HCV NS5B-catalyzed nucleotide incorporation, and identifying inhibitors of HCV replicase. The assay systems use small and well-defined synthetic RNAs which allow efficient assembly of all catalytic components in the quaternary complex for HCV NS5B-directed RNA replication. Specific template-primer requirements for efficient RNA synthesis by HCV NS5B replicase are provided for use in assay systems.

    摘要： The present invention relates to identification of the features of an RNA template that provide for efficient “copy-back” self-priming activity of hepatitis C virus replicase. This activity can be used to screen for anti-HCV replicase compounds, or to characterize the biological relevance of lead compounds that have already been identified. The specific features of the optimal RNA templates can be used for developing a system to characterize HCV NS5B polymerase mechanistically and kinetically, and for designing small RNA molecules to co-crystallize with HCV NS5B polymerase.
