The exoribonuclease acts on ssRNA in a 3' to 5' direction (PubMed:30058998). Most active on dsRNA substrates containing one or two non-paired 3'-terminal nucleotides, thereby probably increasing the fidelity of the viral RNA-dependent RNA polymerase by excising RNA 3'-end mismatches during viral RNA replication (PubMed:30058998).<ref>PMID:30058998</ref> NendoU is a Mn(2+)-dependent, uridylate-specific enzyme, which leaves 2'-3'-cyclic phosphates 5' to the cleaved bond. Catalyzes the RNA 2'-O-ribose methyltransferase reaction to methylate the type-0 cap into the type-1 cap (m)GpppN(m)-RNA.[UniProtKB:P0C6X7] |
