3k2z
From Proteopedia
Crystal structure of a LexA protein from Thermotoga maritima
Function
[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).
