Dehydrogenases involved in conversion of hypoxanthine to xanthine, and xanthine to uric acid, as the final catabolism of purines. Deficient in the human disease xanthinuria.
Xanthine oxidase (XO, sometimes `XAO`) is a form of xanthine oxidoreductase, a type of enzyme that generates reactive oxygen species. These enzymes catalyze the oxidation of hypoxanthine to xanthine and can further catalyze the oxidation of xanthine to uric acid. These enzymes play an important role in the catabolism of purines in some species, .....Found on http://en.wikipedia.org/wiki/Xanthine_oxidase
