Escherichia coli RNA polymerase mutants that enhance or diminish the SOS response constitutively expressed in the absence of RNase HI activity.

Journal of bacteriology - 1 Mar 1994

Kogoma T

Abstract excerpt

Escherichia coli rnhA mutants lacking RNase HI chronically express the SOS response (T. Kogoma, X. Hong, G. W. Cadwell, K. G. Barnard, and T. Asai, Biochimie 75:89-99, 1993). Seventeen rpoB (Rifr) mutant alleles, which encode altered beta subunits of RNA polymerase, giving rise to resistance to rifampin, were screened for the ability to enhance or diminish constitutive expression of the SOS response in rnhA...
