xanthine oxidase
xanthine oxidase[′zan‚thēn ′äk·sə‚dās] (biochemistry) A flavoprotein enzyme catalyzing the oxidation of certain purines. xanthine oxidase
xan·thine ox·i·dasea flavoprotein containing molybdenum; an oxidoreductase catalyzing the reaction of xanthine, O2, and H2O to produce urate and superoxide. Also oxidizes hypoxanthine, some other purines and pterins, and aldehydes. A lower rate of oxidation is observed in patients with molybdenum cofactor deficiency. Synonym(s): hypoxanthine oxidase, Schardinger enzymexan·thine ox·i·dase (zanthēn oksi-dās) Flavoprotein containing molybdenum; also oxidizes hypoxanthine, some other purines and pterins, and aldehydes. Schardinger, Franz, Austrian scientist, 1853-1920. Schardinger dextrins - the result of action of Bacillus macerans on starch.Schardinger enzyme - a flavoprotein containing molybdenum. Synonym(s): xanthine oxidaseSchardinger reaction - an example of oxidation in the absence of O2 with an organic hydrogen acceptor.AcronymsSeeXOThesaurusSeexanthine |
