General description

β-Glucuronidase Type H-2 from Helix pomatia is a crude solution of enzymes derived from the Roman snail. Many β-glucuronidases derived from mollusks also contain sulfatase activity.

Application

β-Glucuronidase from Helix pomatia has been used:
  • to convert isoflavone conjugates to their aglycone forms in urine and soymilk samples for high performance liquid chromatography (HPLC) detection
  • as a component in the protoplasting solution
  • for the generation of aromatic and phenolic compounds from the plasma and urine samples for gas chromatography-mass spectrometry (GC-MS)
  • to hydrolyze glucuronide and sulfate conjugated metabolites in fecal samples

β-glucuronidase was used in the measurement of aromatization by a urine technique suitable for the evaluation of aromatase inhibitors in vivo.

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.
Used for the hydrolysis of glucuronide conjugates in urinary metabolite analysis

Quality

Many β-glucuronidases derived from mollusks also contain sulfatase activity.

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 5.0 (30 min assay).
Sulfatase Unit Definition: One unit of sulfatase will hydrolyze 1.0 μmole p-nitrocatechol sulfate per hr at pH 5.0 at 37 °C.

Physical form

Aqueous solution in ~1.0 M ammonium sulfate with 3 mM sodium azide as preservative.
