Abstract

LuxR is an AHL-dependent activator. However to insert lux box between -35 and -10 and LuxR fuctions as LuxR-AHL inverter. Someone resistered the Plux inverter in Biobrick.We've prepare Plux inv-GFP and characterized about it.

Experiments

1.Preparing Plux inv-GFP

Plasmid:R0061 and E0240
Strain:XL10-G
protocol
Preparing process of Plux inv-GFP is shown in Fig. 1.We transformed preparing Plux inv-GFP in XL10-G and confirmed the expression GFP Fluorescence.The sequence is also conformed.

2.Characterization Plux inv-GFP

Plasmid:Plux inv-GFP and Plac-LuxR (LuxR constitutive generator)
strain:DH10B
protocol
We cotransformded Plux inv-GFP and LuxR Plac-LuxR in DH10B.LB liquid incubate 37゜C,12 h

Results

AHLの有無に関わらず蛍光が観察された。
We confirmed GFP Fluorescence both AHL+ and -sample.
