RT Journal Article SR Electronic T1 A Fluorescent Assay Amenable to Measuring Production of β-d-Glucuronides Produced from Recombinant UDP-Glycosyl Transferase Enzymes JF Drug Metabolism and Disposition JO Drug Metab Dispos FD American Society for Pharmacology and Experimental Therapeutics SP 555 OP 557 VO 27 IS 5 A1 Trubetskoy, Olga V. A1 Shaw, Peter M. YR 1999 UL http://dmd.aspetjournals.org/content/27/5/555.abstract AB β-glucuronidase cleavage of 4-methylumbelliferyl β-d-glucuronide generates the highly fluorescent compound, 4-methylumbelliferone. We show that other β-d-glucuronide compounds act as competitors in this assay. The 4-methylumbelliferyl β-d-glucuronide cleavage assay can easily be adapted to high throughput formats to detect the presence of β-D glucuronides generated using recombinant glycosyl transferase preparations.
