General annotation (Comments)

Function

Key enzyme in purine degradation. Catalyzes the oxidation of hypoxanthine to xanthine. Catalyzes the oxidation of xanthine to uric acid. Contributes to the generation of reactive oxygen species By similarity.

Catalytic activity

Xanthine + NAD+ + H2O = urate + NADH. Ref.1 Ref.2

Hypoxanthine + NAD+ + H2O = xanthine + NADH. Ref.1 Ref.2

Xanthine + H2O + O2 = urate + H2O2. Ref.1 Ref.2

Cofactor

Binds 2 2Fe-2S clusters By similarity.

FAD By similarity.

Binds 1 molybdenum-molybdopterin (Mo-MPT) cofactor per subunit By similarity.

Subunit structure

Homodimer By similarity.

Subcellular location

Peroxisome By similarity. Cytoplasm Ref.2.

Tissue specificity

Detected in liver (at protein level). Ref.2

Sequence similarities

Belongs to the xanthine dehydrogenase family.

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

Contains 1 FAD-binding PCMH-type domain.
