In enzymology, a D-arabinono-1,4-lactone oxidase (EC 1.1.3.37) is an enzyme that catalyzes the chemical reaction

D-arabinono-1,4-lactone + O2 D-erythro-ascorbate + H2O2

Thus, the two substrates of this enzyme are D-arabinono-1,4-lactone and O2, whereas its two products are D-erythro-ascorbate and H2O2.

This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with oxygen as acceptor. The systematic name of this enzyme class is D-arabinono-1,4-lactone:oxygen oxidoreductase. It employs one cofactor, FAD.

The glucose oxidase enzyme also known as notatin is an oxidoreductase that catalyses the oxidation of glucose to hydrogen peroxide and D-glucono-δ-lactone. This enzyme is produced by certain species of fungi and insects and displays antibacterial activity when oxygen and glucose are present.

<small>L</small>-gulonolactone oxidase Enzyme involved in the synthesis of vitamin C

L-Gulonolactone oxidase is an enzyme that produces vitamin C. It is expressed in most mammals, but is non-functional in Haplorrhini, in some bats, and in guinea pigs. It catalyzes the reaction of L-gulono-1,4-lactone with oxygen to form L-xylo-hex-3-gulonolactone (2-keto-gulono-γ-lactone) and hydrogen peroxide. It uses FAD as a cofactor. The L-xylo-hex-3-gulonolactone then converts to ascorbic acid spontaneously, without enzymatic action. The structure of L-gulonolactone oxidase in rats helps identify characteristics of this enzyme.
