Xanthine oxidase is a nicotinamide adenine dinucleotide (NAD)-dependent dehydrogenase, which is converted to oxidase under ischemic conditions utilizing molecular oxygen in place of NAD …

Xanthine oxidase is a metalloflavoprotein that is found in milk fat globules. In milk, this enzyme has several functions. Xanthine oxidase catalyzes the conversion of hypoxanthine to xanthine …

In most living beings, the catabolism of hypoxanthine and xanthine to uric acid is ensured by the xanthine dehydrogenase activity (XDH, EC 1.17.1.4), but only mammals possess the xanthine …

Xanthine oxidase catalyzes the oxidation of hypoxanthine to xanthine and uric acid in a reaction that involves a one-electron transfer to oxygen to yield O 2 •− [234–237]. Xanthine oxidase …

2015年2月23日 · Xanthine oxidase (XO) is an important enzyme catalyzing the hydroxylation of hypoxanthine to xanthine and xanthine to uric acid which is excreted by kidneys. Excessive …
