Rdrp activity regulation
WebRNA-dependent RNA polymerases (RdRPs) encoded by RNA viruses represent a unique class of processive nucleic acid polymerases, carrying out DNA-independent replication/transcription processes. Although viral RdRPs have versatile global structures, they do share a structurally highly conserved active site comprising catalytic motifs A-G.
