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) thereby allowing
CC       the early genes transcription. Late transcription, and probably also
CC       intermediate transcription, require newly synthesized RNA polymerase
CC       (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, 35
CC       kDa, 30 kDa, 22 kDa, 19 kDa, 18 kDa and 7 kDa totalling more than 500
CC       kDa in mass. The same holoenzyme, with the addition of the
CC       transcription-specificity factor RAP94, is used for early gene
CC       expression (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Virion {ECO:0000305}. 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   -!- INDUCTION: Expressed in the early phase of the viral replicative cycle.
CC   -!- SIMILARITY: Belongs to the poxviridae DNA-directed RNA polymerase 7 kDa
CC       subunit family. {ECO:0000305}.
