Protein

LexA repressor

Gene

lexA

Organism
Pseudomonas entomophila (strain L48)
Status
Unreviewed - Annotation score: 3 out of 5- Protein inferred from homologyi

Functioni

Represses a number of genes involved in the response to DNA damage (SOS response), including recA and lexA. 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.UniRule annotation
