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.
The specificity for galactose and other sugars is similar to that described by Avigad.

Other Notes

1 U produziert eine ΔA425 von 1.0 pro Minute bei pH 6.0 und 25 °C in einem Peroxidase und o-Tolidin System. Reaktionsvolumen = 3.4 mL. Lichtweg = 1 cm.

Questions

  1. Hello, I have bought this enzyme for some assays in our lab in January 2024. I would like to ask how this enzyme is produced? Is it recombinant (E. coli or yeast) or is it directly isolated from Dactilium dendroides? Looking forward to hearing from you!

    1 answer
    1. This enzyme is from D. Dendroides and is recombinantly produced from Yeast in an animal component free fermentation process.
