Application

Xanthine-agarose is used for protein chromatography, affinity chromatography and specialty resins. Xanthine-agarose has been used to purify and determine molecular properties of urate oxidase from Chlamydomonas reinhardtii. Xanthine-agarose has also been used to determine physicochemical properties and states of sulfhydryl groups of uricase from Candida utilis.

Caffeine biosynthesis comprises sequential methylations at N-7, N-3 and N-1 of the xanthine ring catalysed by S-adenosyl-L-methionine (SAM)-dependent methyltransferase activities that, to date, have not been resolved. Enzyme extracts were prepared from young, emerging coffee leaflets and following anion exchange

Urate oxidase (Uox) catalyses the first reaction of oxidative uricolysis, a three-step enzymatic pathway that allows some animals to eliminate purine nitrogen through a water-soluble compound. Inactivation of the pathway in hominoids leads to elevated levels of sparingly soluble urate

Uricase (urate: oxygen oxidoreductase; EC 1.7.3.3) from the rust Puccinia recondita was purified to electrophoretic homogeneity. Preparations with a specific activity of 8.4 U/mg were used for characterization of the enzyme, which showed a strong similarity to other plant and
