Usage and biology:

In QS system, the upstream product gets higher concentration as the population grows, which then regulates activity of the downstream promoter. In this part, LuxR activator protein combines with homoserine lactone(HSL) produced by LuxI as dimers. The dimers then up-regulate the expression of luxpR.

Design:

QS system is the main regulating circuit in our project. After comparing the efficiency of different QS system，we chose LuxI and LuxR to regulate the downstream circuit. To balance and stabilize the copy number of luxI (BBa_C0061) and luxR(BBa_C0062), we designed this plasmid carrying the two gene at the same time. Both gene uses the J23106 promoter and B0015 terminator. As a upstreaming plasmid for inducing, its measurement needs to cooperate with another downstream QS promoter (luxpR-EsfGFP in our experiment).

Final dimeric production regulating luxpr

In QS system, the upstream product gets higher concentration as the population grows, which then regulates activity of the downstream promotor. In this part, LuxR activator protein combines with homoserine lactone(HSL) produced by LuxI protein as dimers. The dimers then up-regulate the expression of luxpr.
