TIME DELAY1.0:LuxI(RBS1.0)->LuxR->LuxPR->GFP
Description
This part contains BBa_K750001 and BBa_K750007. Arabinose will activate the promoter Pbad, which will cause production of protein LuxI and LuxR. The protein LuxI will synthesize a small, diffusible signaling molecule acyl-homoserinelactone(AHL). The AHL accumulates as the cell density increases. At sufficiently high concentrations, it binds the LuxR, which induces the expression of our reporter GFP under the control of a promoter lux pR. Expression of LuxI will be affected when strength of RBS before LuxI gene is changed. When expression of LuxI is weak, speed of AHL production will go down, that means it costs longer time for AHL-LuxR to arrive the activation thrshold of the promoter LuxPR. In the time delay part of our project E.Lumoli, we designed 4 circuit with RBSes of different strength in the LuxI producer to construct a time delay device. And this part, TD1.0, reacts faster than other circuits we designed(TD0.6:BBa_K750010,TD0.01:BBa_K750012).
