CC -!- FUNCTION: Catalytic component of the DNA-directed RNA polymerase (RNAP)
CC that catalyzes the transcription in the cytoplasm of viral DNA into RNA
CC using the four ribonucleoside triphosphates as substrates (By
CC similarity). Forms the polymerase active center together with RPB1 (By
CC similarity). Part of the core element with the central large cleft, the
CC clamp element that moves to open and close the cleft and the jaws that
CC are thought to grab the incoming DNA template (By similarity).
CC {ECO:0000250|UniProtKB:P30876}.
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=2.7.7.6;
CC -!- SUBUNIT: Part of the viral DNA-directed RNA polymerase that consists of
CC 8 polII-like subunits (RPB1, RPB2, RPB3, RPB5, RPB6, RPB7, RPB9,
CC RPB10), a capping enzyme and a termination factor.
CC {ECO:0000250|UniProtKB:P42487}.
CC -!- SUBCELLULAR LOCATION: Host cytoplasm {ECO:0000305}. Virion
CC {ECO:0000250|UniProtKB:P42487}. Note=Found in association with viral
CC nucleoid. {ECO:0000250|UniProtKB:P42487}.
CC -!- INDUCTION: Expressed in the late phase of the viral replicative cycle.
CC {ECO:0000305}.
CC -!- MISCELLANEOUS: The binding of ribonucleoside triphosphate to the RNA
CC polymerase transcribing complex probably involves a two-step mechanism.
CC The initial binding seems to occur at the entry (E) site and involves a
CC magnesium ion coordinated by three conserved aspartate residues of the
CC two largest RNA Pol subunits. {ECO:0000250|UniProtKB:P30876}.
CC -!- SIMILARITY: Belongs to the RNA polymerase beta chain family.
CC {ECO:0000305}.
