Prokaryotic RNA Polymerases consist of two α subunits, a β, β ’, ω, and σ subunits. Although RNA polymerase was discovered in 1960, the E. coli RNAP has not yet been successfully mapped by x-ray crystallography. However, it is very similar to the RNAP of the archaean species, Thermophilus aquaticus, which is highly stable ...
