General description

β-Glucuronidase Type H-2 from Helix pomatia is a crude solution of enzymes derived from the digestive juices of the Roman snail. β-glucuronidases derived from mollusks often contain sulfatase activity. Both activities are useful in the hydrolysis of metabolites for toxicology and biomarker analysis. For a broader look at our β-Glucuronidase product line and their uses see our page about Drug Metabolite Analysis

Application

  • Sample preparation for LC/MS through digestion of glucuronide conjugated compounds for biomarker and toxicology research.
  • Removal of glucuronide conjugates such as for the preparation of Baicalein.­

Biochem/physiol Actions

Endogenous beta-glucuronidase is a lysosomal enzyme involved in digestion of glucuronide-modified catabolites.
Microbial beta-glucuronidase found in microbiota can cause re-absorption of metabolites by hydrolysis of glucuronide conjugates of xenobiotic and endobiotic metabolites.
Used for the hydrolysis of glucuronide conjugates in urinary metabolite analysis

Features and Benefits

  • pH optima 4.0 - 5.0.
  • Sulfatase pH optima 6.2
  • Low Sulfatase activity (<7,500 units/mL).
  • Ammonium Sulfate suspension.
  • Mollusk-derived beta-glucuronidase.
  • Useful for acidic hydrolysis of glucuronides in low pH samples.

Quality

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

Linkage

Similar to G0876, but produced by Sigma.

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.
