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.

This work was done by M.M, X.T and S.L.

To characterize Plux-LasI (BBa_K934022), we introduced Plux-LasI pSB3K3 with Ptet-LuxR (BBa_S03119) on pSB6A1 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”.

When the supernatants of the culture of “3OC6HSL dependent 3OC12HSL producer cell” were induced to “Las reporter cell”, GFP expression in “Las reporter cell” was activated. This result shows that Plux-lasI(K934022) is functioning.

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

This work was done by M.M, X.T and S.L.
