General annotation (Comments)

Function

Key enzyme in purine degradation. Catalyzes the oxidation of hypoxanthine to xanthine. Catalyzes the oxidation of xanthine to uric acid By similarity.

Catalytic activity

Xanthine + NAD+ + H2O = urate + NADH.

Hypoxanthine + NAD+ + H2O = xanthine + NADH.

Cofactor

Binds 2 2Fe-2S clusters By similarity.

FAD By similarity.

Binds 1 molybdenum ion (molybdopterin) per subunit By similarity.

Subcellular location

Peroxisome By similarity.

Induction

By 2-thiouric acid. Repressed by ammonium. Ref.1

Sequence similarities

Belongs to the xanthine dehydrogenase family.

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

Contains 1 FAD-binding PCMH-type domain.
