β-Glucuronidase from Helix pomatia

一般描述

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.

生物活性/药理作用

Used for the hydrolysis of glucuronide conjugates in urinary bolite 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

应 用

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

有效单位定义

One modified Fishman unit will liberate 1.0μg of phenolphthalein from phenolphthalein glucuronide per hr at 37°C at pH5.0 (30 min assay).

Sulfatase Unit Definition: One unit of sulfatase will hydrolyze 1.0μmole p-nitrocatechol sulfate per hr at pH5.0  at 37°C.
