The effect of the cellular level of RecA protein on the ability of E. coli K12 bacteria to (i) survive UV-irradiation (ii) promote UV-reactivation of UV-damaged phage lambda (iii) induce prophage lambda was determined in bacterial mutants with discrete increasing levels of RecA protein. The various
In UV-irradiated cells of Escherichia coli K-12 a partial release of the restriction of non-modified phage 2 is observed when the cells are recA + lexA +. We show here that the induction of this restriction allevation (RA) also depends on the recBC enzyme and that the expression of RA requires prote
