New insights into purine metabolism in metabolic diseases: role of xanthine oxidoreductase activity.
American Journal of Physiology. Endocrinology and Metabolism, 2020Xanthine oxidoreductase (XOR) consists of two different forms, xanthine dehydrogenase (XDH) and xanthine oxidase (XO), and is a rate-limiting enzyme of uric acid production from hypoxanthine and xanthine. Uric acid is the end-product of purine metabolism

Titanium carbide quantum dots (Ti3C2 QDs) derived from 2D Ti3C2Tx (MXene) are the rising-star material recently. Herein, a nitrogen-doped Ti3C2 QDs (N-Ti3C2 QDs) were synthesized via a solvothermal method.

Bovine thyroidal xanthine oxidase
International Journal of Biochemistry, 1978Abstract 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.

[Xanthine oxidase (xanthine dehydrogenase)].
Nihon rinsho. Japanese journal of clinical medicine, 1997Xanthine 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).

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.

Fluorometric assay for xanthine oxidase
Analytical Biochemistry, 1967Abstract It has been shown that the fluorometric assay for xanthine oxidase, in which 2-amino-4-hydroxypteridine (AHP) is oxidized to a fluorescent product, is not valid when applied to fresh extracts of rat liver. The reaction rate is not proportional to the amount of enzyme preparation in the range of substrate and tissue concentration recommended ...

Inhibition of xanthine oxidase by pterins
Free Radical Research, 1998The effect of a panel of pterins on xanthine oxidase was investigated by measuring formation of urate from xanthine as well as formazan production from nitroblue tetrazolium. The pterin derivatives, depending on their chemical structure, decreased urate as well as formazan generation: 200 microM neopterin and biopterin suppressed urate formation (90 ...

Myocardial xanthine oxidase/dehydrogenase
Biochimica et Biophysica Acta (BBA) - Molecular Cell Research, 1983High-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.
