Application

β-Glucuronidase from bovine liver has been used in β-glucuronidase inhibition assay to study the β-glucuronidase inhibitory effect of extracts and isolated actives from Phyllanthus amarus. It has also been used to perform deglucuronidation.
β-glucuronidase is used as a reporter gene in GUS assays to monitor gene expression.

Biochem/physiol Actions

β-Glucuronidase (GUSB) deficiency can result in mucopolysaccharidosis type VII (MPSVII), which leads to store lysosome in the brain. Integration of β-glucuronides of steroid hormones into tissues can be done with the help of GUSB.
β-glucuronidase catalyzes the breakdown of complex carbohydrates. In humans it converts conjugated bilirubin into the unconjugated form, making bilirubin suitable for reabsorption.

General description

β-Glucuronidase (GUSB) is a lysosomal enzyme, found in animals, plants and bacteria. This exoglycosidase shows high activity in spleen, liver and kidney. Bovine liver β-glucuronidase (BLG) is homotetramer with a molecular weight of 290 kDa.

Other Notes

One Sigma or 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).
