Purification and properties of chicken liver xanthine dehydrogenase.


Chicken liver xanthine dehydrogenase, which catalyzes the reduction of DPN+ by various purines and aldehydes, was purified to near homogeneity. It exhibits a molecular weight of about 300,000, a molar complement, flavin to molybdenum to iron to labile sulfide, of 2:2:8:8, and an absorption spectrum resembling those of milk xanthine oxidase and rabbit liver… (More)
