UniProt functional annotation for Q5SHR6

UniProt code: Q5SHR6.

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.
 
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;
Subunit: Homodimer. 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 (By similarity). {ECO:0000250}.
Domain: The N-terminal domain is essential for RNAP assembly and basal transcription, whereas the C-terminal domain is involved in interaction with transcriptional regulators and with upstream promoter elements. {ECO:0000250}.
Similarity: Belongs to the RNA polymerase alpha chain family. {ECO:0000305}.
