The reactions of chloroperoxidase in the presence of xanthine/xanthine oxidase
Biochemical and Biophysical Research Communications, 1989Spectral data are presented which indicate that chloroperoxidase is converted to compound II during the reaction with superoxide/hydrogen peroxide generated in the xanthine/xanthine oxidase system. Upon completion of compound II formation, compound II returns back to the native state of chloroperoxidase without formation of detectable intermediates. It

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 ...

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. XO/XD activity is, for example,

Xanthine Oxidase and Virus Growth
Nature, 1947So far as is known, viruses appear to possess no enzyme activity ; the virus particles, in order to multiply, must presumably utilize the enzyme-substrate reactions of the host cells, or else have a selective affinity for the products of host metabolism.
