Pyranose Oxidase from Coriolus sp., recombinant, expressed in E. coli, >=2.7 units/mg solid

Pyranose Oxidase from Coriolus sp., recombinant, expressed in E. coli, >=2.7 units/mg solid

Application

Pyranose Oxidase from Coriolus sp. has been used in the enzymatic oxidation of D-glucose (DG). It has also been used as a component in oxygen scavenging system (OSS) to increase the lifetime of the fluorophores.

Biochem/physiol Actions

Pyranose oxidase (P2O) catalyzes the oxidation of aldopyranoses at position C-2 to yield the corresponding 2-ketoaldoses. The in vivo substrates of P2O are thought to be D-glucose, D-galactose, and D-xylose. They are oxidized to 2-keto-D-glucose (D-arabino-hexos-2-ulose, 2-dehydro-D-glucose), 2-keto-D-galactose (D-lyxo-hexos-2-ulose, 2-dehydro-D-galactose), and 2-keto-D-xylose (D-threopentos-2-ulose, 2-dehydro-D-xylose), respectively. Pyranose oxidase has significant activity with carbohydrates such as, L-sorbose, D-glucono-1,5-lactone, and D-allose. When pyranose oxidase catalyzes the oxidation of aldopyranoses, electrons are transferred to molecular oxygen which results in the formation of hydrogen peroxide.

Pyranose oxidase (P2O) can be used in clinical chemistry to determine 1,5-anhydro-d-glucitol marker, used for glycemic control in diabetes patients.

General description

Pyranose oxidase (P2O), a homotetrameric protein consists of a covalently bound flavin adenine dinucleotide (FAD). It is seen mostly among wood-degrading basidiomycetes.
