Inhibition of the transcriptional repressor LexA: Withstanding drug resistance by inhibiting the bacterial mechanisms of adaptation to antimicrobials.

Life Sciences, 2019
LexA protein is a transcriptional repressor which regulates the expression of more than 60 genes belonging to the SOS global regulatory network activated by damages to bacterial DNA. Considering its role in bacteria, LexA represents a key target to counteract bacterial resistance: the possibility to modulate SOS response through the inhibition of LexA ...

The LexA repressor binds within the deep helical groove of the activated RecA filament.

Journal of Molecular Biology, 1993
The RecA protein of Escherichia coli, as a result of DNA damage, catalyzes the cleavage of its own repressor, the LexA protein, and thereby initiates the SOS response.
