CC -!- FUNCTION: DNA-dependent RNA polymerase catalyzes the transcription of
CC DNA into RNA using the four ribonucleoside triphosphates as substrates.
CC {ECO:0000256|ARBA:ARBA00004026, ECO:0000256|HAMAP-Rule:MF_00059}.
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; Evidence={ECO:0000256|ARBA:ARBA00024550,
CC ECO:0000256|HAMAP-Rule:MF_00059};
CC -!- SUBUNIT: In plastids the minimal PEP RNA polymerase catalytic core is
CC composed of four subunits: alpha, beta, beta', and beta''. When a
CC (nuclear-encoded) sigma factor is associated with the core the
CC holoenzyme is formed, which can initiate transcription.
CC {ECO:0000256|HAMAP-Rule:MF_00059}.
CC -!- SUBCELLULAR LOCATION: Plastid, chloroplast {ECO:0000256|HAMAP-
CC Rule:MF_00059}.
CC -!- DOMAIN: The N-terminal domain is essential for RNAP assembly and basal
CC transcription, whereas the C-terminal domain is involved in interaction
CC with transcriptional regulators and with upstream promoter elements.
CC {ECO:0000256|HAMAP-Rule:MF_00059}.
CC -!- SIMILARITY: Belongs to the RNA polymerase alpha chain family.
CC {ECO:0000256|ARBA:ARBA00007123, ECO:0000256|HAMAP-Rule:MF_00059}.
