In a rifS/rifR heterodiploid strain of E. coli, a 4 minute pulse of rifampicin can induce a prolonged (greater than 60 min) increase in the rate of synthesis of the RNA polymerase subunits, beta and beta'. The application of a constraint on the fidelity of protein synthesis during, but not after, th

We have examined the level of expression of the SOS regulon in cells lacking DNA adenine methylase activity (darn-). Mud (Ap, lac) fusions to several SOS operons (recA, lexA, uvrA, uvrB, uvrD, sulA, dinD and dinF) were found to express higher levels of fl-galactosidase in darn-strains than in isogen
