| xanthine dehydrogenase |
[EC 1.1.1.204] an enzyme of the oxidoreductase class that catalyzes the hydroxylation of xanthine or hypoxanthine to urate, using NAD+ as an electron acceptor. The enzyme is a molybdoflavoprotein with a bound FAD and two iron-sulfur centers. Under certain conditions the enzyme is converted to a form that can reduce molecular oxygen and is called xanthine oxidase. Deficiency of enzyme activity, due to isolated defect in the enzyme or to molybdenum cofactor deficiency (q.v.), results in xanthinuria and deposition of xanthine calculi.

| xanthine oxidase |
[EC 1.1.3.22] an enzyme of the oxidoreductase class that catalyzes the oxidation of hypoxanthine to xanthine and of xanthine to uric acid, the final steps in the degradation of purines. It is an iron-molybdenum flavoprotein containing FAD. Deficiency of the enzyme, an autosomal recessive trait, causes xanthinuria.
