Cryo-EM structure of Pseudomonas aeruginosa Recombinase A (RecA) in complex with LexAS125A mutantCryo-EM structure of Pseudomonas aeruginosa Recombinase A (RecA) in complex with LexAS125A mutant
Structural highlights
FunctionLEXA_PSEAE 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. |
