Plas-LuxI

We constructed this part by combining BBa_K649000 and BBa_K081008. This part generates LuxI enzyme in the presence of LasR-3OC12HSL complex.

To characterize Plas-LuxI (BBa_K934012), we introduced Plas-LuxI (BBa_K934012) with Ptrc-LasR to E.coli as “3OC12HSL dependent 3OC6HSL producer cell”. In this E.coli, constitutively expressed LasR activates the expression of LuxI in the presence of 3OC12HSL. We then introduced Ptet-LuxR (BBa_S03119) and Plux-GFP (BBa_K395100) to E.coli as a “Lux reporter cell”.

In the presence of 3OC6HSL produced by “3OC12HSL dependent 3OC6HSL producer cell”, GFP expression in “Lux reporter cell” was activated. Thus, the expression of GFP in “Lux reporter cell” is regulated by 3OC6HSL produced by “3OC12HSL dependent 3OC6HSL producer cell”, this result shows that Plas-LuxI (BBa_K934012) synthesized 3OC6HSL.

We improved a previous part Plas-LuxI (BBa_K266000) and accomplished a positive feedback system with our new Plux-LasI (BBa_K934022).
