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
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
Plux inv-GFP およびLuxR generatorである Plac-LuxRをDH10B株に共形質転換した。コロニーをつついてLB液体培地(AHL0および1000 nM)で12 h培養し, スピンダウンしてペレットを観察した。 We cotransformded Plux inv-GFP and LuxR generator,Plac-LuxR in DH10B.

Results
AHLのありおよびなしに関わらず蛍光が観察された。
We confirmed
