| + | == Function == | ||
| + | [https://www.uniprot.org/uniprot/LEXA_THEMA LEXA_THEMA] 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 (By similarity). | ||
