Short name=RNAP subunit beta
EC=2.7.7.6
Alternative name(s):
RNA polymerase subunit beta
Transcriptase subunit beta
Gene names
Name:rpoB
Ordered Locus Names:TTHA1813
OrganismThermus thermophilus (strain HB8 / ATCC 27634 / DSM 579) [Reference proteome] [HAMAP]
Taxonomic identifier300852 [NCBI]
Taxonomic lineageBacteriaDeinococcus-ThermusDeinococciThermalesThermaceaeThermus

Protein attributes

Sequence length1119 AA.
Sequence statusComplete.
Protein existenceEvidence at protein level

General annotation (Comments)

Function

DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. HAMAP-Rule MF_01321

Catalytic activity

Nucleoside triphosphate + RNA(n) = diphosphate + RNA(n+1). HAMAP-Rule MF_01321

Subunit structure

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.

Sequence similarities

Belongs to the RNA polymerase beta chain family.
