Plux-LasI

We constructed this part by combining BBa_R0062 and BBa_K081016. This part produces LasI enzyme in the presence of LuxR-3OC6HSL complex.

To characterize Plux-LasI (BBa_K934022), we introduced Plux-LasI (BBa_K934022) with Ptet-LuxR (BBa_S03119) to E.coli as “3OC6HSL dependent 3OC12HSL producer cell”. In this E.coli, constitutively expressed LuxR activates the expression of LasI in the presence of 3OC6HSL. We then introduced Ptrc-LasR and Plas-GFP (BBa_K649001) to E.coli as a “Las reporter cell”.

In the presence of 3OC12HSL produced by “3OC6HSL dependent 3OC12HSL producer cell”, “Las reporter cell” was activated and GFP was expressed. Thus, the expression of GFP in “Las reporter cell” is dually regulated by 3OC12HSL produced by “3OC6HSL dependent 3OC12HSL producer cell”, this result shows that Plux-lasI(K934022) synthesized 3OC12HSL.

We accomplished a positive feedback system with our improved part Plux-LasI(BBa_K934012). Please see Experience page.
