Extracellular phosphate sensor with GFP reporter

PhoB and PhoR proteins are part of the Pho regulon inherent in E.coli. When low concentration of extracellular phosphate ions is present, PhoR can phosphorylate PhoB to form active phosphorylated-PhoB. PhoB promoter is activated as a result of active binding of phosphorylated-PhoB, resulting in downstream expression of GFP. When high concentration of extracellular phosphate ions is present, PhoR will dephosphorylate phosphorylated-PhoB, and therefore inactivating it, and repressing PhoB promoter for downstream expression of GFP.
