Glucose oxidase — An overview

Biotechnology Advances, 2009
Glucose oxidase (beta-D-glucose:oxygen 1-oxidoreductase; EC 1.1.2.3.4) catalyzes the oxidation of beta-D-glucose to gluconic acid, by utilizing molecular oxygen as an electron acceptor with simultaneous production of hydrogen peroxide. Microbial glucose oxidase is currently receiving much attention due to its wide applications in chemical ...

Specificity of glucose oxidase

Archives of Biochemistry and Biophysics, 1960
Abstract The specificity of glucose oxidase for catalyzing the oxidation of β- d -glucose in contrast to α- d -glucose, other hexoses, and pentoses was investigated. The enzyme appears to catalyze the oxidation of the beta form only, and the mutarotation of the alpha form is rate limiting.

Immobilized Glucose Oxidase in the Potentiometric Detection of Glucose

Applied Biochemistry and Biotechnology, 1984
Previous work has shown that glucose oxidase can be immobilized on platinum to give an electrode that responds potentiometrically to glucose over the clinically useful range of about 10-250 mg glucose/100 mL. The present studies were carried out with electrochemically pretreated platinum and with gold or porous graphite substituted for the platinum ...

Immunologic Properties of Glucose Oxidase

The Journal of Immunology, 1970
Abstract Glucose oxidase, an anzyme obtained from Aspergillus niger, is a potent antigen. Guinea pigs and rabbits immunized with this antigen in complete Freund's adjuvant produced high serum concentrations of precipitating antibody. In addition, heat-inactivated enzyme and apoenzyme can be used to detect cellular immunity in the guinea ...

Inkjet delivery of glucose oxidase

Chemical Communications, 2010
The activity of glucose oxidase is reduced by inkjet printing and is a function of the printing conditions. Standard characterisation methods show no significant change to enzyme molecular weight, secondary structure and general molecular shape as a function of printing parameters.

Effects of glucose oxidase in mice

Biochemical Pharmacology, 1964
Abstract The effects of glucose oxidase, which oxidizes glucose and produces H2O2, were studied in mice after intraperitoneal injection of supralethal doses of the enzyme. Such injections cause the appearance of hematin pigment in the plasma, up to 20 per cent of this pigment being methemoglobin.

Some studies of glucose oxidase

Archives of Biochemistry and Biophysics, 1961
Abstract A commercial preparation of glucose oxidase is shown to oxidize d -glucose, d -galactose, d -mannose, and d -xylose at relative rates which are pH dependent. The product of these reactions is the corresponding glyconic acid which in each case is identified as the crystalline γ-lactone and amide.

Glucose oxidase of Phanerochaete chrysosporium

1988
Publisher Summary Glucose oxidase catalyzes the oxidation of D-glucose to δ-D-gluconolactone and H 2 O 2 in the presence of molecular oxygen. In a subsequent step δ -D-gluconolactone is nonenzymatically hydrolyzed to D-gluconic acid. This enzyme has been demonstrated in various Aspergillus and Penicillium species and has recently been purified ...

Studies on conditions for the polarographic determination of glucose with glucose oxidase

Clinica Chimica Acta, 1972
Abstract Results are presented on the effect of several variables on a method for the determination of glucose using a polarograph with a Clark-type O 2 electrode and glucose oxidase. Glucose concentration [ G ] was proportional to the rate of O 2 consumption |− Δ O 2 / Δt | in the 5–800 μg/ml range.
