EC number

1.2.3.4

Accepted name

oxalate oxidase

Reaction

oxalate + O₂ + 2 H⁺ = 2 CO₂ + H₂O₂

Other name(s)

aero-oxalo dehydrogenase, oxalic acid oxidase

Systematic name

oxalate:oxygen oxidoreductase

CAS registry number

9031-79-2

Comment

Contains Mn²⁺ as a cofactor. The enzyme is not a flavoprotein as had been thought [3].
