General description
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.
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.
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.

Essentially no oxidation of D-glucose, L-galactose, L-arabinose or D-glucuronate has been observed.
The specificity for galactose and other sugars is similar to that described by Avigad.
Other Notes
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.

Irinotecan (CPT11), a broad-spectrum cytotoxic anticancer agent, induces a series of toxic side-effects. The most conspicuous side-effect is gastrointestinal mucositis, including nausea, vomiting, and diarrhea. A growing body of evidence indicates that bacteria β-glucuronidase (GUS), an enzyme expressed by intestinal

Galactose oxidase (GOase) was shown to oxidise several C2/C3 fluorinated galactose analogues. Interestingly, the enzyme was able to distinguish between the 2,3-tetrafluorinated galactose and its epimeric glucose analogue, and this represents the first reported biotransformation of a heavily fluorinated sugar.
