Description
In enzymology, an alcohol oxidase (EC 1.1.3.13) is an enzyme that catalyzes the chemical reaction:a primary alcohol + O2↔ an aldehyde + H2O2. Thus, the two substrates of this enzyme are primary alcohol and O2, whereas its two products are aldehyde and H2O2. This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with oxygen as acceptor. It employs one cofactor, FAD.
Abbr
Alcohol Oxidase, Native (Hansenula sp.)
Alias
alcohol oxidase; ethanol oxidase
Applications
Alcohol oxidase is used to catalyze the oxidation of short-chain, primary, aliphatic alcohols to their respective aldehydes. It may be used to study methanol metabolism is yeasts, such as Candida, Pichia, and Hansenula. It is useful to study protein translocation into peroxisomes.
