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 β-glucuronidase obtained from Patella vulgate.

Analysis Note

Contains sulfatase activity which is inhibited by 0.1 M phosphate.

Other Notes

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).

Naltrexone is effective in treating opioid dependence by blocking µ, κ and δ opiate receptors. Naltrexone is mainly metabolized to an active metabolite 6β-naltrexol by dihydrodiol dehydrogenase enzymes. Concomitant opioids will not be effective while patients are taking this antagonist.
