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

PEGylation is a successful strategy for improving the biochemical and biopharmaceutical properties of proteins and peptides through the covalent attachment of polyethylene glycol chains. In this work, purified recombinant uricase from Candida sp. (UC-r) was modified by PEGylation with metoxypolyethilenoglycol-p-nitrophenyl-carbonate
Isolation and characterization of uricase from bean leaves and its comparison with uredospore enzymes.
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 from leaves: its purification and characterization from three different higher plants.
