show Brenda entry

EC number

1.1.3.47

Accepted name

5-(hydroxymethyl)furfural oxidase

Reaction

5-(hydroxymethyl)furfural + 3 O₂ + 2 H₂O = furan-2,5-dicarboxylate + 3 H₂O₂ (overall reaction);;(1a) 5-(hydroxymethyl)furfural + O₂ = furan-2,5-dicarbaldehyde + H₂O₂;;(1b) furan-2,5-dicarbaldehyde + H₂O = 5-(dihydroxymethyl)furan-2-carbaldehyde (spontaneous);;(1c) 5-(dihydroxymethyl)furan-2-carbaldehyde + O₂ = 5-formylfuran-2-carboxylate + H₂O₂;;(1d) 5-formylfuran-2-carboxylate + H₂O = 5-(dihydroxymethyl)furan-2-carboxylate (spontaneous);;(1e) 5-(dihydroxymethyl)furan-2-carboxylate + O₂ = furan-2,5-dicarboxylate + H₂O₂

Systematic name

5-(hydroxymethyl)furfural:oxygen oxidoreductase

Comment

The enzyme, characterized from the bacterium Methylovorus sp. strain MP688, is involved in the degradation and detoxification of 5-(hydroxymethyl)furfural. The enzyme acts only on alcohol groups and requires the spontaneous hydration of aldehyde groups for their oxidation [3]. The enzyme has a broad substrate range that overlaps with EC 1.1.3.7, aryl-alcohol oxidase.
