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

Highly purified uricase [urate: oxygen oxidoreductase, EC 1.7.3.3] was obtained from Candida utilis by affinity chromatography with xanthine-agarose conjugate followed by chromatography with Sephadex G-200 in the presence of dithiothreitol. The uricase molecule had a molecular weight of 120,000 and

Urate oxidase (urate: oxygen oxidoreductase, EC 1.7.3.3) from the unicellular green alga Chlamydomonas reinhardtii has been purified to electrophoretic and immunological homogeneity by a procedure which includes as main steps ammonium sulfate fractionation, gel filtration, ion exchange and xanthine-agarose affinity

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

The G-protein coupled receptors (GPCRs) are a class of membrane proteins that trigger cellular responses to external stimuli, and are believed to be targets for nearly half of all pharmaceutical drugs on the market. However, little is known regarding their
