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. Morphine 3-β-D glucuronide was converted to morphine using ß-glucuronidase obtained from Patella vulgate.


Contains sulfatase activity which is inhibited by 0.1 M phosphate.

Definición de unidad
