UniProt functional annotation for Q8RQE8

UniProt code: Q8RQE8.

Organism: Thermus thermophilus (strain ATCC 27634 / DSM 579 / HB8).
Taxonomy: Bacteria; Deinococcus-Thermus; Deinococci; Thermales; Thermaceae; Thermus.
 
Function: DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. {ECO:0000255|HAMAP-Rule:MF_01322}.
 
Catalytic activity: Reaction=a ribonucleoside 5'-triphosphate + RNA(n) = diphosphate + RNA(n+1); Xref=Rhea:RHEA:21248, Rhea:RHEA-COMP:11128, Rhea:RHEA- COMP:11129, ChEBI:CHEBI:33019, ChEBI:CHEBI:61557, ChEBI:CHEBI:83400; EC=2.7.7.6; Evidence={ECO:0000255|HAMAP-Rule:MF_01322};
Cofactor: Name=Mg(2+); Xref=ChEBI:CHEBI:18420; Evidence={ECO:0000255|HAMAP-Rule:MF_01322}; Note=Binds 1 Mg(2+) ion per subunit. {ECO:0000255|HAMAP-Rule:MF_01322};
Cofactor: Name=Zn(2+); Xref=ChEBI:CHEBI:29105; Evidence={ECO:0000255|HAMAP-Rule:MF_01322}; Note=Binds 2 Zn(2+) ions per subunit. {ECO:0000255|HAMAP- Rule:MF_01322};
Subunit: The RNAP catalytic core consists of 2 alpha, 1 beta, 1 beta' and 1 omega subunit. When a sigma factor is associated with the core the holoenzyme is formed, which can initiate transcription. {ECO:0000255|HAMAP-Rule:MF_01322}.
Similarity: Belongs to the RNA polymerase beta' chain family. {ECO:0000255|HAMAP-Rule:MF_01322}.
