NarP Nitrate/Nitrite Sensor
NarP with gfp
Lambert iGEM’s novel NarP system BBa_K3411020 is also modeled after E.coli’s natural nitrite sensor in the NAR Operon. Similarly to NarL, the promoter BBa_J23106, a constitutive Anderson Promoter, produces TetR, which represses the PtetO promoter, producing NarP. By regulating the amount of aTc, the molecule that inhibits TetR, our lab can control NarP’s expression, the product of the PtetO promoter. NarQ, the native membrane-bound protein, senses the amount of nitrate and/or nitrite in the cell: In the presence of nitrite and/or nitrate, NarQ will phosphorylate NarP, activating it, but if there is no nitrite and/or nitrate present, NarQ will not phosphorylate NarP. If NarP is phosphorylated, it will activate the nirB promoter, producing GFP.
Lambert iGEM plans on cloning and characterizing our NarP composite part in the coming year as a part of our two-year project, AgroSense.
