E. coli RNA Polymerase, Core Enzyme


E. coli RNA Polymerase, Core Enzyme consists of 5 subunits designated α, α, β´, β, and ω.

  • Free of sigma factor and does not recognize any specific bacterial or phage DNA promoters.
  • Retains the ability to transcribe RNA from nonspecific initiation sequences.
  • Addition of sigma factors will allow the enzyme to initiate RNA synthesis from specific bacterial and phage promoters.
  • The core enzyme has a molecular weight of approximately 400 kDa.
