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. 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).
