| 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.
