Novel mechanism for UV sensitivity and apparent UV nonmutability of recA432 mutants: persistent LexA cleavage following SOS induction.

Journal of bacteriology - 1 Nov 1993

Ennis D G, Little J W, Mount D W

Abstract excerpt

The recA432 mutant allele was isolated (T. Kato and Y. Shinoura, Mol. Gen. Genet. 156:121-131, 1977) by virtue of its defect in cellular mutagenesis (Mut-) and its hypersensitivity to damage by UV irradiation (UVs), which were phenotypes expected for a recA mutant. However, we found that in a different genetic background (lexA51 sulA211 uvrB+), recA432 mutants expressed certain mutant phenotypes but not the Mut-...
