Application

β-glucuronidase was used in enzymic hydrolysis of tissue homogenates for liquid chromatography-electrospray ion trap mass spectrometry (LC/MSn) analysis, to study the structures of degradation products of baicalin.[1]

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[2][3][4].

Unit Definition

One Sigma or modified Fishman unit will liberate 1.0 μg of phenolphthalein from phenolphthalein glucuronide per hr at 37°C at the pH 5.0 (30 min assay).
One unit of sulfatase will hydrolyze 1.0 μmole p-nitrocatechol sulfate per hr at pH 5.0 at 37 °C.

Other Notes

Used for the hydrolysis of glucuronide conjugates in urinary metabolite analysis
