Repressor LexA.
based on mapping to UniProt O33927
Hydrolysis of Ala-|-Gly bond in repressor LexA.
-!- In the presence of single-stranded DNA, the RecA protein 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. -!- The activity was previously attributed to the RecA protein (formerly EC 3.4.99.37). -!- Belongs to peptidase family S24.
