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.
Abbr
Galactose Oxidase, Recombinant (Dactylium dendroides)
Source
Dactylium dendroides
Applications
GaO has been shown to be useful in a number of biotechnology and medical applications which include monitoring of galactose in blood and urine, paper strengthening additives, test strips for cancer diagnosis, biosensors and lactose detection, dental care and hair coloring and waving.
Product Overview
Galactose oxidase (GaO) is a recombinantly expressed copper activated enzyme derived from Dactylium dendroides that catalyzes the stereospecific oxidation of D-isomer primary alcohols to aldehydes and hydrogen peroxide (1-3). GaO has a range of substrates that include D-galactose and polysaccharides, glycolipids, or glycoproteins with D-galactose at their non-reducing end.
