OX NCBI_TaxID=2056412 {ECO:0000313|EMBL:WAN86538.1}; RN [1] {ECO:0000313|EMBL:WAN86538.1} RP NUCLEOTIDE SEQUENCE. RA Yang F.; RL Submitted (JUL-2022) to the EMBL/GenBank/DDBJ databases. 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}.
