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}.
