RA Kong H., Liu W., Yao G., Gong W.; RT "Characterization of the whole chloroplast genome of a rare and RT endangered species Aconitum reclinatum (Ranunculaceae) in the United RT States."; RL Conserv Genet Resour 0:0-0(2017). CC -!- FUNCTION: DNA-dependent RNA polymerase catalyzes the transcription CC of DNA into RNA using the four ribonucleoside triphosphates as CC substrates. {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:11128, Rhea:RHEA- CC COMP:11129, ChEBI:CHEBI:33019, ChEBI:CHEBI:61557, CC ChEBI:CHEBI:83400; EC=2.7.7.6; Evidence={ECO:0000256|HAMAP- CC Rule:MF_01321, ECO:0000256|RuleBase:RU363031}; CC -!- SUBUNIT: In plastids the minimal PEP RNA polymerase catalytic core CC is composed of four subunits: alpha, beta, beta', and beta''. When CC a (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 ECO:0000256|SAAS:SAAS01158605, ECO:0000256|SAAS:SAAS01158606}. CC -!- SUBCELLULAR LOCATION: Plastid, chloroplast {ECO:0000256|HAMAP- CC Rule:MF_01321}. CC -!- SIMILARITY: Belongs to the RNA polymerase beta chain family. CC {ECO:0000256|HAMAP-Rule:MF_01321, ECO:0000256|RuleBase:RU000434}.
