生物活性/药理作用

D-fructose dehydrogenase 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.

应 用

This enzyme is also used in a number of  basic research projects to examine the electrochemical properties of enzyme-catalyzed electrode reactions called bioelectrocatalysis.This enzyme is useful for enzymatic determination of D-fructose in clinical analysis.

有效单位定义

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