Biotin oxidation
Web[Show full abstract] biotin, oxidation of both carbons bridging the ureido to thiophane rings occurs, producing urea which is degraded to CO2 and NH, by urease. The relatively high radioactivity ... WebBy switching the modification of interest to a biotin moiety, these assays leverage the high affinity between biotin and avidin to enrich the modification. The use of stable isotope labeling and a range of selective reducing agents facilitate the quantitation of individual as well as total reversible cysteine oxidation.
