Parent Class:

EC-Numbers → 1 -- Oxidoreductases → 1.2 -- Acting on the aldehyde or oxo group of donors → 1.2.3 -- With oxygen as acceptor

Synonyms: aero-oxalo dehydrogenase, oxalic acid oxidase

Systematic Name: oxalate:oxygen oxidoreductase

Unification Links: BRENDA:1.2.3.4, ENZYME:1.2.3.4, IUBMB-ExplorEnz:1.2.3.4

Reaction:
oxalate + dioxygen + 2 H⁺ → 2 CO₂ + hydrogen peroxide

Enzymes and Genes:
oxalate oxidase: oxo1 ( Hordeum vulgare )

Summary:
Contains Mn2⁺ as a cofactor. The enzyme is not a flavoprotein as had been thought [Requena99].
