Long Description: We plan to develop a system that can sense a low level of nitrate in water by using a mutant of nitrate-inducible fnr coupled with the narG promoter. While normally only inducible under anaerobic conditions, a single silent mutation to convert leucine-28 to histidine can allow the fnr gene to operate under anaerobic conditions. The fnr gene acts as a promoter for narG, which can send a PoPs-out signal to a GFP reporter. Previous studies have shown that the mutated form of fnr can sense nitrate at as low as 0.1 uM. | Long Description: We plan to develop a system that can sense a low level of nitrate in water by using a mutant of nitrate-inducible fnr coupled with the narG promoter.
