The protein
Basic information/ Evolution
- Catalyzed reaction/ biological activity: Represses dinA, dinB, dinC, recA genes and itself by binding to the 14 bp palindromic sequence 5'-CGAACNNNNGTTCG-3'. In the presence of single-stranded DNA, RecA interacts with LexA causing an autocatalytic cleavage which disrupts the DNA-binding part of LexA, leading to derepression of the SOS regulon and eventually DNA repair.
