Application

β-Glucuronidase Type L-II has been shown to be a superior enzyme for the hydrolysis of drug-glucuronides from urine.
New Technical Article Comparing Performance of Different Enzymes
Learn more about recent application data generated by Sigma R&D to optimize hydrolysis for different drug classes using enzymes from different sources and the use of a chromatographicaly purified enzyme to reduce the effect of esterase activity resulting in conversion of 6-MAM to Morphine
The enzyme from patella vulgata is reported to be more effective in hydrolyzing opioid-glucuronides than the Helix pomatia, bovine liver and E. coli enzymes

Biochem/physiol Actions

β-glucuronidase (β-GIc) is an exoglycosidase that catalyzes the breakdown of complex carbohydrates. In humans it converts conjugated bilirubin into the unconjugated form, making bilirubin suitable for reabsorption. Morphine 3-β-D glucuronide was converted to morphine using ß-glucuronidase obtained from Patella vulgate.

Quality

Contains sulfatase activity which is inhibited by 0.1 M phosphate.

Unit Definition

One Sigma or modified Fishman unit will liberate 1.0 μg of phenolphthalein from phenolphthalein glucuronide per hr at 37 °C at pH 3.8 (30 min assay).

beta-Glucuronidase from Patella vulgata, Helix aspersa, Helix pomatia, and bovine liver were evaluated for usefulness in routine hydrolysis of drug-glucuronic acid conjugates from equine urine samples. Factors affecting the reaction rate (enzyme concentration, ligand concentration, temperature, and pH) were optimized.
