lexA1

Gene
lexA1
Protein
LexA repressor 1
Organism
Nocardia farcinica (strain IFM 10152)
Length
216 amino acids
Function
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.
Similarity
Belongs to the peptidase S24 family.
