2.7.7.48 | nucleoside triphosphate + RNAn | DNA can serve as a template for ZIKV NS5 with an efficiency similar to that of an RNA template. The enzyme (NS5) can utilize single-stranded DNA but not double-stranded DNA as a template or a primer to synthesize RNA. Both full-length NS5 and a truncated NS5 containing the polymerase domain can carry out in vitro RNA-dependent RNA synthesis | Zika virus | diphosphate + RNAn+1 | - |
