Quorum-Sensing Receiver Construct

Transformed cells with this construct respond to AHL-dependent quorum sensing and GFP would be expressed by the activated transcription factor protein LuxR which binds to the bidirectional promoter region (pLuxR/pLuxI).

Biology and Usage

This Receiver part contains the V. fischeri-intrinsic bidirectional promoter region, the LuxRS regulon. The high concentration of Acyl-homoserine lactose (AHL) binds to the LuxR protein to activate and it binds to pLuxR/pLuxS promoters. Instead of LuxS protein, we add super folder GFP in order to make this part as the reporter part of the whole system (Fig 1). The super folder GFP is followed by the PixCell degradation tag from the 2018 Imperial College team to analyze the reporter gene spatiotemporally.
