UDP-glucuronosyltransferases (UGTs) and β-glucuronidase (GUS) catalyze entirely distinct metabolism reactions. UGTs are responsible for the glucuronidation of a variety of drugs, endogenous and environmental chemicals, whereas GUS hydrolyzes glucuronides and liberates the parent substrates.

Enzymatic Assay of β-Glucuronidase (EC 3.2.1.31) from E. coli

Using UHPLC/MS (TOF) for Detection of Drugs and Metabolites in Urine Following Optimized Enzymatic Hydrolysis Conditions

To optimize hydrolysis using β-glucuronidase, factors such as incubation time, temperature, hydrolysis pH, enzyme source, and enzyme concentration must be evaluated for each glucuronide metabolite to be analyzed.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
