RT "Complete structure of the chloroplast genome of Populus alba.";
RL Submitted (MAR-2005) 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:0000255|HAMAP-Rule:MF_01324}.
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_01324};
CC -!- COFACTOR:
CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01324};
CC Note=Binds 1 Zn(2+) ion per subunit. {ECO:0000255|HAMAP-Rule:MF_01324};
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_01324}.
CC -!- SUBCELLULAR LOCATION: Plastid, chloroplast {ECO:0000255|HAMAP-
CC Rule:MF_01324}.
CC -!- SIMILARITY: Belongs to the RNA polymerase beta' chain family. RpoC2
CC subfamily. {ECO:0000255|HAMAP-Rule:MF_01324}.
