"We functionally analyzed the role of metal ions in RNA-dependent RNA synthesis by three recombinant RNA-dependent RNA polymerases (RdRps) from GB virus-B (GBV), bovine viral diarrhea virus (BVDV), and hepatitis C virus (HCV), with emphasis on the HCV RdRp. Using templates capable of both de novo initiation and primer extension and RdRps purified in the absence of metal, we found that only reactions with exogenously provided Mg2+ and Mn2+ gave rise to significant amounts of synthesis. Magnesium (Mg2+) and manganese (Mn2+) affected the...
