CC   -!- FUNCTION: RNA-dependent RNA polymerase which is found both free and
CC       covalently attached to the genomic RNA. May also contain guanylyl and
CC       methyl transferase activities (By similarity). {ECO:0000250}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=a ribonucleoside 5'-triphosphate + RNA(n) = diphosphate +
CC         RNA(n+1); Xref=Rhea:RHEA:21248, Rhea:RHEA-COMP:14527, Rhea:RHEA-

CC         EC=2.7.7.48; Evidence={ECO:0000255|PROSITE-ProRule:PRU00539};
CC   -!- SUBUNIT: Interacts with VP3 in the cytoplasm. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Virion {ECO:0000250}. Note=Minor amounts are
CC       incorporated in the virion. {ECO:0000250}.
CC   -!- PTM: May exist in multiple phosphorylated forms.
