ENZYME entry: EC 3.4.21.88

Accepted Name
repressor LexA
Reaction catalysed
Hydrolysis of Ala-|-Gly bond in repressor LexA
Comment(s)
  • 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.
