General annotation (Comments)

Function

This enzyme can be converted from the dehydrogenase form (D) to the oxidase form (O) irreversibly by proteolysis or reversibly through the oxidation of sulfhydryl groups By similarity.

Catalytic activity

Xanthine + NAD+ + H2O = urate + NADH.

Hypoxanthine + NAD+ + H2O = xanthine + NADH.

Xanthine + H2O + O2 = urate + H2O2.

Cofactor

Binds 2 2Fe-2S clusters By similarity.

FAD By similarity.

Molybdopterin By similarity.

Subunit structure

Homodimer. Interacts with BTN1A1 By similarity.

Subcellular location

Peroxisome By similarity.

Sequence similarities

Belongs to the xanthine dehydrogenase family.

Contains 1 2Fe-2S ferredoxin-type domain.

Contains 1 FAD-binding PCMH-type domain.
