CC -!- FUNCTION: RNA-dependent RNA polymerase, which is responsible for the
CC replication and transcription of the viral RNA genome using antigenomic
CC RNA as an intermediate. During transcription, synthesizes subgenomic
CC RNAs and assures their capping by a cap-snatching mechanism, which
CC involves the endonuclease activity cleaving the host capped pre-mRNAs.
CC These short capped RNAs are then used as primers for viral
CC transcription. The 3'-end of subgenomic mRNAs molecules are
CC heterogeneous and not polyadenylated. The replicase function is to
CC direct synthesis of antigenomic and genomic RNA which are encapsidated
CC and non capped. As a consequence of the use of the same enzyme for both
CC transcription and replication, these mechanisms need to be well
CC coordinated. These processes may be regulated by proteins N and Z in a
CC dose-dependent manner. {ECO:0000255|HAMAP-Rule:MF_04086}.
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|HAMAP-Rule:MF_04086};
CC -!- COFACTOR:
CC Name=Mn(2+); Xref=ChEBI:CHEBI:29035;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_04086};
CC Note=For endonuclease activity. Binds 2 Mn(2+) ions in the active site.
CC The divalent metal ions are crucial for catalytic activity.
CC {ECO:0000255|HAMAP-Rule:MF_04086};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_04086};
CC Name=Mn(2+); Xref=ChEBI:CHEBI:29035;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_04086};
CC Note=For polymerase activity. {ECO:0000255|HAMAP-Rule:MF_04086};
CC -!- SUBUNIT: Homomultimer; the oligomeric structure is essential for the
CC polymerase activity. Interacts with nucleoprotein N. Interacts with
CC protein Z; this interaction inhibits viral transcription and
CC replication. {ECO:0000255|HAMAP-Rule:MF_04086}.
CC -!- SUBCELLULAR LOCATION: Virion {ECO:0000255|HAMAP-Rule:MF_04086}. Host
CC cytoplasm {ECO:0000255|HAMAP-Rule:MF_04086}.
CC -!- DOMAIN: The N-terminus contains the endonuclease activity (endoN). The
CC central region contains the RdRp activity. {ECO:0000255|HAMAP-
CC Rule:MF_04086}.
CC -!- MISCELLANEOUS: Classified as His(-) endonuclease since it does not have
CC a histidine upstream of the active site that coordinates the first
CC cation. His(-) endonucleases display very low activity in vitro,
CC although they are clearly active in vivo. {ECO:0000255|HAMAP-
CC Rule:MF_04086}.
CC -!- SIMILARITY: Belongs to the Bunyavirales RNA polymerase family.
CC {ECO:0000255|HAMAP-Rule:MF_04086}.
