CC   -!- FUNCTION: Part of the DNA-dependent RNA polymerase which catalyzes the
CC       transcription of viral DNA into RNA using the four ribonucleoside
CC       triphosphates as substrates. Responsible for the transcription of
CC       early, intermediate and late genes. DNA-dependent RNA polymerase
CC       associates with the early transcription factor (ETF), itself composed
CC       of D6 and A7, thereby allowing the early genes transcription. Late
CC       transcription, and probably also intermediate transcription, require
CC       newly synthesized RNA polymerase (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         COMP:17342, ChEBI:CHEBI:33019, ChEBI:CHEBI:61557, ChEBI:CHEBI:140395;
CC         EC=2.7.7.6;
CC   -!- SUBUNIT: The DNA-dependent RNA polymerase used for intermediate and
CC       late genes expression consists of eight subunits (147) kDa, (133) kDa,
CC       (35) kDa, (30) kDa, (22) kDa, (19) kDa, (18) kDa and (7) kDa totalling
CC       more than 500 kDa in mass. The same holoenzyme, with the addition of
CC       the transcription-specificity factor RAP94, is used for early gene
CC       expression (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Virion {ECO:0000250}. Note=All the enzymes and
CC       other proteins required to synthesize early mRNAs are packaged within
CC       the virion core along with the DNA genome. This is necessary because
CC       viral early mRNAs are synthesized within minutes after virus entry into
CC       the cell and are extruded through pores in the core particle (By
CC       similarity). {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the RNA polymerase beta chain family.
CC       {ECO:0000305}.
