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.

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.
