CC -!- FUNCTION: Replicase large subunit: is an RNA-dependent RNA
CC polymerase active in viral RNA replication. {ECO:0000250}.
CC -!- FUNCTION: Replicase small subunit: is a methyltransferase active
CC in RNA capping and an RNA helicase. Methyltransferase displays a
CC cytoplasmic capping enzyme activity. This function is necessary
CC since all viral RNAs are synthesized in the cytoplasm, and host
CC capping enzymes are restricted to the nucleus. Helicase region
CC probably exhibits NTPase and RNA unwinding activities (Potential).
CC {ECO:0000305}.
CC -!- CATALYTIC ACTIVITY: ATP + H(2)O = ADP + phosphate.
CC -!- CATALYTIC ACTIVITY: Nucleoside triphosphate + RNA(n) = diphosphate
CC + RNA(n+1). {ECO:0000255|PROSITE-ProRule:PRU00539}.
CC -!- SUBUNIT: Heterodimer of a large and a small subunit.
CC {ECO:0000250}.
CC -!- MISCELLANEOUS: The replicase large subunit is translated as a
CC fusion protein by episodic readthrough of a termination codon.
CC When readthrough of the terminator codon TGA occurs between the
CC codons for 1187-Lys and 1189-Arg, this results in the addition of
CC the RdRp region.
CC -!- SIMILARITY: Belongs to the ssRNA positive-strand viruses RNA-
CC directed RNA polymerase family. {ECO:0000305}.
CC -!- SIMILARITY: Contains 1 (+)RNA virus helicase ATP-binding domain.
CC {ECO:0000305}.
CC -!- SIMILARITY: Contains 1 (+)RNA virus helicase C-terminal domain.
CC {ECO:0000305}.
CC -!- SIMILARITY: Contains 1 alphavirus-like MT (methyltransferase)
CC domain. {ECO:0000255|PROSITE-ProRule:PRU01079}.
CC -!- SIMILARITY: Contains 1 RdRp catalytic domain.
CC {ECO:0000255|PROSITE-ProRule:PRU00539}.
