Abstract:
LexA2 repressor was partially inactivated after mitomycin C or UV light treatment in a recA+ or recA85(Prtc) (protease constitutive) host background. LexA2 protein was cleaved, but the reaction was slower than that observed for LexA+ repressor. lexA2 had a C-to-T transition at nucleotide 461 (Thr-154 to Ile).
