The gene
Basic information
- Locus tag: BSU17850
Phenotypes of a mutant
Database entries
- DBTBS entry: [1]
- SubtiList entry: [2]
Additional information
The protein
Basic information/ Evolution
- Catalyzed reaction/ biological activity: Represses uvrB, 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. (according to Swiss-Prot)
- Protein family: peptidase S24 family (according to Swiss-Prot)
