| Biochem/physiol Actions: | The specificity for galactose and other sugars is similar to that described by Avigad. |
| 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. |
