Fig. 4From: Identification and biochemical characterization of the fructokinase gene family in Arabidopsis thaliana Putative Arabidopsis FRKs specifically phosphorylate fructose. Graphs of [NADH] vs time in coupled enzyme assays in the presence of carbohydrate mixes of (a) Fructose-6-phosphate (F6P), Sucrose (Suc), and N-Acetyl-D-mannoseamine (N-AcDMannosamine). b Ribose (Rib), Xylose (Xyl), and Arabinose (Ara). c Glucose (Glu), Fructose (Fru), Fucose (Fuc), and Tagatose (Tag). Graphs of [NADH] vs time in coupled enzyme assays in the presence of single carbohydrates (d) Fucose (e) Glucose (f) Tagatose and (g) Fructose. Experiments were repeated at least twice with two technical replicas per experimentBack to article page
