Bot. 44:32-40(2019). 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_01321, CC ECO:0000256|RuleBase:RU363031}. 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_01321, ECO:0000256|RuleBase:RU363031}; 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_01321, ECO:0000256|RuleBase:RU363031}. CC -!- SUBCELLULAR LOCATION: Plastid, chloroplast CC {ECO:0000256|ARBA:ARBA00004229, ECO:0000256|HAMAP-Rule:MF_01321}. CC -!- SIMILARITY: Belongs to the RNA polymerase beta chain family. CC {ECO:0000256|ARBA:ARBA00006835, ECO:0000256|HAMAP-Rule:MF_01321, CC ECO:0000256|RuleBase:RU000434}.
