Highly purified Escherichia coli RNA polymerase contains a small subunit termed omega. This subunit consists of 91 amino acids with a molecular weight of 10,105. We previously reported the cloning and sequencing of the gene encoding omega, which we call rpoZ (D. R. Gentry and R. R. Burgess, Gene 48:33-40, 1986). We constructed an rpoZ insertion mutation by placing a kanamycin resistance cassette into the coding region of the rpoZ gene. Purified RNA polymerase from strains carrying this mutation… CONTINUE READING
