Product Name

Galactose Oxidase from Dactylium dendroides

General deion

Galactose oxidase is an extracellular copper-containing enzyme, secreted by the deuteromycete fungus Dactylium dendroides. It catalyzes the oxidation of a range of primary alcohols, including D-galactose, to the corresponding aldehyde, with reduction of oxygen to hydrogen peroxide.

l Biological Information

Biochem/Physiol Actions

Galactose oxidase catalyzes the coversion of D-galactose to D-galacto-hexodialdose. 2-Deoxy-D-galactose, lactose, melibiose, raffinose and stachyose react with galactose oxidase in the peroxidase:o-tolidine system. Essentially no oxidation of D-glucose, L-galactose, L-arabinose or D-glucuronate has been observed.

Application

Galactose oxidase may be used as an analytical tool for the specific determination of D-galactose in blood plasma, plant extracts, and phospholipids. It could be used for the characterization of terminal D-galactoside units in several polymers.

Unit Definition

One unit will produce a ΔA⁴²⁵ of 1.0 per min at pH 6.0 at 25 °C, in a peroxidase and o-tolidine system. Reaction volume = 3.4 mL. Light path = 1 cm.
