3.A.1.2.29
High affinity fructose uptake porter, FrtABC, Km (fructose) = ~100μM; expression of the frtABC operon is regulated by the product of the upstream gene, frtR, FrtR, a LacI/GalR-type repressor that allows activation in the presence of fructose (Ungerer et al. 2008). When FruR is eliminated, the cells become hypersensitive to fructose, and the level of fruABC expression is much higher than in the presence of wild type cells grown on fructose (Ungerer et al. 2008).
