Question

Identify and describe the roles of the different subunits of the E.coli RNA polymerase, including how each of them interacts with the other polymerase subunits and with the various promoter elements

Answer 1

The subunits of the E. coli RNA polymerase include two alpha (α) subunits, beta subunit, β' subunit and ω subunit.

What is the E. coli RNA polymerase?

The E. coli RNA polymerase is a macromolecular complex that this bacterium uses to synthesize RNA during the process of transcription.

The α subunits of the RNA polymerase are required to assemble this complex in the promotor region during the initiation step.

The beta subunits of the RNA polymerase are required during RNA synthesis (transcription).

The omega (ω) subunit of the RNA polymerase is required to associate the σ factor with the enzymatic core complex.

These subunits bind each other in order to form a core enzymatic complex that interact with a specific nucleotide sequence (i.e., the TATA box) of promoter regions.

In conclusion, the subunits of the E. coli RNA polymerase include two alpha (α) subunits, beta subunit, β' subunit and ω subunit.
