Expression of GFP and of the timer device under the control of the LexA-controlled promoter

Induced by the SOS response (LexA dependent) upon DNA damages (UV, mitomycin…). This promoter allow the expression of the operon caa and cal. caa gene is coding for Colicin A (ColA) a toxin toxin produced by E. coli strains, and active against other non-immune E.coli strains. In this contruction GFP permit to understand the mechanism, and ColA isn't able to have his toxin activity. To protect themselfs, E. coli have an imumnity protein coded by cai gene (-). cal gene is codding for a lysis protein, when this protein is produce ColA can be delivered in the extracellular medium after the E. coli cells lysis. The regulation is complex and involves many regulatory elements: terminator (+) and (-), promoters, antisense coding sequence, etc.
