Beschreibung
Zusammenfassung:	Disclosed are systems, components, and methods for sensing a ligand in a cell or a reaction mixture. The disclosed systems, components, and methods may include and/or utilize a fusion protein comprising a ligand-binding protein and a DNA-binding protein. The fusion protein binds the ligand of the ligand-binding protein and modulates expression of a reporter gene operably linked to a promoter that is engineered to include specific binding sites for the DNA-binding protein. The difference in expression of the reporter gene in the presence of the ligand versus expression of the reporter gene in the absence of the ligand can be correlated to the concentration of the ligand in a reaction mixture.
