D-fructose dehydrogenase is used as a biosensor to detect the presence of D-fructose.

Fructose dehydrogenase (FDH) is used in a number of basic research projects to examine the electrochemical properties of enzyme-catalyzed electrode reactions called bioelectrocatalysis. D-fructose dehydrogenase has been used in a study that contributed towards a convenient method for measuring rare sugars, monosaccharides, for applications in the bio-industry. A direct electron transfer reaction of d-fructose dehydrogenase adsorbed on a porous carbon electrode surface has been used to describe a batch-type coulometric d-fructose biosensor.

Biochem/physiol Actions

D-fructose dehydrogenase catalyzes the oxidation of D-fructose to 5-keto-D-fructose.

Fructose dehydrogenase (FDH) is a heterotrimeric membrane-bound enzyme commonly seen in various Gluconobacter sp. especially in Gluconobacter japonicus (Gluconobacter industrius). It has a molecular mass of ca. 140 kDa, consisting of subunits I (67kDa), II (51 kDa), and III (20 kDa) and catalyzes the oxidation of D-fructose to produce 5-keto-D-fructose. The enzyme is a flavoprotein-cytochrome c complex with subunits I and II covalently bound to flavin adenine dinucleotide (FAD) and heme C as prosthetic groups, respectively.
