Protein existenceInferred from homology

General annotation (Comments)

Function

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. HAMAP-Rule MF_00015 SAAS SAAS006199

Catalytic activity

Hydrolysis of Ala-|-Gly bond in repressor lexA. HAMAP-Rule MF_00015 RuleBase RU003992 SAAS SAAS006199

Subunit structure

Homodimer By similarity. HAMAP-Rule MF_00015 SAAS SAAS006199

Sequence similarities

Belongs to the peptidase S24 family. HAMAP-Rule MF_00015 RuleBase RU003991
