β-Glucuronidases are routinely used for the enzymatic hydrolysis of glucuronides from Serum plasma and other fluids prior to analysis by enzyme immunoassay, mass spectrometry, gas chromatography, high performance liquid chromatography, or other means. β-glucuronidase is used as a reporter gene in GUS assays to monitor gene expression.

β-glucuronidase catalyzes the breakdown of complex carbohydrates. In humans it converts conjugated bilirubin into the unconjugated form, making bilirubin suitable for reabsorption. β-Glucuronidase from Helix pomatia is a mixture of enzymes. Inhibitors: D-glucuronic acid, D-galacturonic acid, D-glucaro-1, 4-lactone.

Unit definition: amount that liberates 1.0 µg of phenolphthalein from phenolphthalein glucuronide per hour at pH 5.0 and 37°C.

Human β-glucuronidase is a type of glucuronidase that catalyzes hydrolysis of β-D-glucuronic acid residues from the non-reducing end of mucopolysaccharides such as heparan sulfate. In human gut β-glucuronidase converts conjugated bilirubin to the unconjugated form for reabsorption.
