Components of the RNA polymerase

Core subunits

• RpoA: alpha subunit
• RpoB: beta subunit
• RpoC: beta' subunit

• The stoichiometry of the enzyme is RpoA(2)-RpoB-RpoC

Sigma factors

• In addition to the housekeeping sigma factor, SigA, there are several other sigma factors with different promoter recognition specifiity that are active under specific conditions (such as stress or sporulation)

Small accessory subunits

• RpoE: delta subunit
• YloH: omega subunit

Other interaction partners

• NusA: essential elongation factor
• GreA: resolve promoter proximal pausing of RNA polymerase PubMed
• CshA

Temporary interaction partners

• Spx: transcription regulator, interacts with RpoA
• MgsR: transcription regulator orthologous to Spx, interacts with RpoA

• Additional interaction partners of the RNA polymerase (no specific subunit specified)
  • HelD, PcrA, TopA, YvqA, RnhC, CshA, YpsC, Mfd, YpiA, YdjO, ResD PubMed
