Aplicación

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.

Acciones bioquímicas o fisiológicas

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.

Definición de unidad

One unit will convert 1.0 μmole D-fructose to 5-ketofructose per min at pH 4.5 at 37 °C.

This paper describes a batch-type coulometric d-fructose biosensor based on direct electron transfer reaction of d-fructose dehydrogenase (FDH) adsorbed on a porous carbon electrode surface. The adsorbed-FDH electrodes catalyzed the electrochemical two-electron oxidation of d-fructose to 5-keto-d-fructose without a mediator.

Several microorganisms are reported to have transfructosylation activity due to fructosyltransferase and/or fructofuranosidase activities. However, the search for other fungi with higher transfructosylation activity remains a challenge. So, a presumptive and indirect colorimetric plate assay for the evaluation of transfructosylation

Nanostructured carbons have been widely used for fabricating enzyme-modified electrodes due to their large specific surface area. However, because they are random aggregates of particular or tubular nanocarbons, the postmodification of enzymes to their intrananospace is generally hard to control.

A biosensor for fructose determination was used as basis of an assay for the determination of glucosyltransferase (GTF) activities and applied to monitoring recombinant enzyme production. GTFs catalyze the synthesis of glucans from sucrose leading to the release of fructose.
