== Function ==
[https://www.uniprot.org/uniprot/LEXA_ECOLI LEXA_ECOLI] Represses a number of genes involved in the response to DNA damage (SOS response), including recA and lexA. Binds to the 16 bp palindromic sequence 5'-CTGTATATATATACAG-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.<ref>PMID:7027255</ref> <ref>PMID:7027256</ref>
