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.

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.

Unit Definition

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).

Protocols

Enzymatic Assay of ß-Glucuronidase (EC 3.2.1.31) from Helix Pomatia and Bovine Liver. This procedure applies to all b-Glucuronidase products that are derived from Helix Pomatia and Bovine Liver. It is the responsibility of trained Analytical Services laboratory personnel to follow this procedure as written.

To optimize hydrolysis using β-glucuronidase, factors such as incubation time, temperature, hydrolysis pH, enzyme source, and enzyme concentration must be evaluated for each glucuronide metabolite to be analyzed.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
