Fumarate-Nitrate Reductase

FNR (fumarate nitrate reductase regulator) is a transcriptional regulator that functions as an O2 sensor. Under anoxic conditions FNR is in the active state and is found as a homodimer. When O2 is present FNR is converted into a monomer which is no longer active (Reinhart, et al., 2008). Therefore co-expression of FNR when hypoxic promoters are used would help to have a more sensitive hypoxic response. Activity is proven by comparing the expression of GFP (BBa_E0040) by promoters with and without the simultaneous expression of the FNR protein.
