Xanthine Oxidase Studies†

Journal of the American Pharmaceutical Association (Scientific ed.), 1952
An investigation was undertaken of the effect on the purine metabolism of the rat of 2-amino-4-hydroxy-6-formyl pteridine, known to inhibit xanthine oxidase, and sodium bromide, reported to retard uricopoiesis. Neither the intraperitoneal administration of the pteridine nor the oral administration of sodium bromide significantly lowered the tissue ...

Xanthine oxidase and xanthine dehydrogenase

The FASEB Journal, 1995
Xanthine oxidase and xanthine dehy‐drogenase are enzymes involved in the metabolism of purines and pyrimidines in various organisms. Their relationship to one another has been the subject of considerable debate, primarily because of their proposed roles in ischemia/reperfasion damage in tissues.

Bovine thyroidal xanthine oxidase

International Journal of Biochemistry, 1978
Abstract 1. 1. Xanthine oxidase from bovine thyroid glands was purified 1000-fold. Electrophoresis of the purified enzyme yielded a single enzymatically active band. 2. 2. A molecular weight of 260,000 ± 20,000 was estimated by gel filtration and by polyacrylamide gel electrophoresis. 3. 3.

Myocardial xanthine oxidase/dehydrogenase

Biochimica et Biophysica Acta (BBA) - Molecular Cell Research, 1983
High-energy phosphates in heart muscle deprived of oxygen are rapidly broken down to purine nucleosides and oxypurines. We studied the role of xanthine oxidase/dehydrogenase (EC 1.2.3.2/EC 1.2.1.37) in this process with novel high-pressure liquid chromatographic techniques.

Sulfhydryl oxidase-catalyzed conversion of xanthine dehydrogenase to xanthine oxidase

Archives of Biochemistry and Biophysics, 1981
Abstract Xanthine oxidase may be isolated from various mammalian tissues as one of two interconvertible forms, viz., a dehydrogenase (NAD+ dependent, form D) or an oxidase (O2 utilizing, form O). A crude preparation of rat liver xanthine dehydrogenase (form D) was treated with an immobilized preparation of crude bovine sulfhydryl oxidase.

Xanthine oxidase

2000
Abstract Xanthine oxidoreductase is widely distributed among mammalian species and is expressed mainly in vascular endothelial cells, hepatocytes, epithelial cells of the intestine, and the secretory cells of the mammary gland. Expression of the enzymatic activity of XO/XD depends on the animal species.

[Xanthine oxidase (xanthine dehydrogenase)].

Nihon rinsho. Japanese journal of clinical medicine, 1997
Xanthine oxidase (xanthine dehydrogenase) is composed of two identical subunits of approximately 150,000 daltons. Each subunit contains four oxdation-reduction active cofactors/monomers. In vivo, the enzyme exists mostly as the dehydrogenase type (the NAD-dependent type).
