Description
a fast degrading GFP ligated to the rear of a sulA promoter in 408 form (only recognizable by our LexA-VVD fusing protein, not by E.coli endogenous LexA). The sulA promoter promotes a gene which express SulA protein, a differentiation inhibitor, and was a member of the SOS regulon family. When co-transformed with our luminesensor plasmid into E.coli cell illuminated by blue light, the light will triger the dimerizaiton of the LexA408-VVD fusion protein and the dimerized LexA408 domain will bind the SOS box in 408 form in the SulA408 promoter to inhibit the transcription of the downstream gene so that no GFP will be expressed; if the environment is dark, the luminesensor will not dimerize and no supression of the promoter will occour, and GFP will be expressed.Notes
