Question

Quizplus · Accepted Answer

Xanthine dehydrogenase (XDH) can be converted to xanthine oxidase (XO) under certain conditions, such as cell damage. This conversion can occur through the formation of a disulfide bond or by proteolysis. In healthy tissues, XDH is the predominant form, but it can be converted to XO, which is more commonly found under conditions of cellular stress or damage.
