Abstract excerpt
rnhA224 and rnhA339::cat mutants which lack RNase HI activity were found to constitutively express the sfiA::lacZ operon fusion in a recA+ lexA(+)-dependent manner. The sfiA::lacZ expression (indicating SOS induction) in rnhA mutants was increased to higher levels by the introduction of the recD1903 or recB21 mutation. The SOS induction in these cells was further enhanced by nutritional shift up from casamino...
