CC   -!- FUNCTION: DNA-dependent RNA polymerase catalyzes the transcription of
CC       DNA into RNA using the four ribonucleoside triphosphates as substrates.
CC       {ECO:0000255|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:0000255|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:0000255|HAMAP-Rule:MF_00059}.
CC   -!- SUBCELLULAR LOCATION: Plastid, chloroplast.
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:0000255|HAMAP-Rule:MF_00059}.
CC   -!- SIMILARITY: Belongs to the RNA polymerase alpha chain family.
CC       {ECO:0000255|HAMAP-Rule:MF_00059}.
