aqueous solution

Physical form

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

l Biological Information

Biochem/Physiol Actions

Used for the hydrolysis of glucuronide conjugates in urinary metabolite analysis

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 derived from the Roman snail.

Optimal pH:

• Glucuronidase activity: 4.5 to 5.0

• Sulfatase activity: ~6.2

Inhibitors: D-glucuronic acid, D-galacturonic acid, D-glucaro-1, 4-lactone

Application

β-glucuronidase is used as a reporter gene in GUS assays to monitor gene .

Unit Definition

One 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.
