Normal induction of the SOS response in Bacillus subtilis is prevented by the mutant repressor from phage φ105cts23
The presence of the Φ105cts23 mutant prophage in Bacillus subtilis induces a series of pleiotropic effects that could be ascribed to an anti-SOS activity. In order to circumvent the phage function responsible for this phenomenon, the cts23 mutant repressor was cloned and sequenced. The isolated repr...
