Opis

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 was used to hydrolyze conjugated glucuronide and sulfate metabolites.

β-Glucuronidase from Helix pomatia has been used:

• in the enzymatic treatment of urine samples for liquid chromatography-electrospray ionization-tandem mass spectrometry (LC-ESI-MS/MS) analysis
• in the quercetin extraction procedure from pig or rat tissues for high performance liquid chromatography (HPLC) analysis
• in the enzymatic deconjugation step in urine and plasma sample preparation for gas chromatography-mass spectrometry analysis (GC-MS)

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

Analysis Note

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

Other Notes

A further purification of G0876 by gel permeation chromatography.

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.
