Design & Experience
In iGEM2020 TPR_China Project, an aromatic sensor was constructed using Pa promoter, the eGFP (BBa_K3599016) and the sfGFP (BBa_K3599017) were both used as downstream reporters to form the sensor devices. To sense the aromatic compounds, PaaX under J23114 constitutive promoter was used together.
The fluorescence of the sensor induced by small molecules
Through the corresponding small molecule sensing experiment, except Dmpr sensor, all our sensors have great induction effects on its corresponding aromatic small molecules. Among which NahR-sfGFP was the best! It is 63 times of the negative control.And here we can see that Xyls-sfGFP is 18 times of the Xyls-GFP( BBa_K1031911). And what surprises us is that Paax sensor also has a good response effect to small molecules, which has not been detected before.
The fluorescence of the sensor induced by PAN
And here is the fluorescence of different sensors induced by PAN.This data shows the same result that NahR-sfGFP responded best.
