CC -!- FUNCTION: RNA-directed RNA polymerase that is involved in transcription
CC and genome replication. Following infection, it catalyzes the synthesis
CC of fully conservative plus strands. After core assembly, which consists
CC in recruitment of one capped plus-strand for each genomic segments and
CC polymerase complexes, the polymerase switches mode and catalyzes the
CC synthesis of complementary minus-strands.
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 COMP:17342, ChEBI:CHEBI:33019, ChEBI:CHEBI:61557, ChEBI:CHEBI:140395;
CC EC=2.7.7.48; Evidence={ECO:0000255|PROSITE-ProRule:PRU00539};
CC -!- SUBCELLULAR LOCATION: Virion {ECO:0000305}. Note=Found in the inner
CC capsid (12 copies).
CC -!- SIMILARITY: Belongs to the reoviridae RNA-directed RNA polymerase
CC family. {ECO:0000305}.
