Opis

General description

β-Glucuronidase is a tetramer belonging to the glycosidase family with a molecular weight of 29 kDa. It is composed of 74 kDa identical monomers. The pI and optimal pH of the enzyme is 4.8 and 6-7 respectively.[1]

Application

β-Glucuronidase was used in the study of Cer-β-glucuronide synthesis and evaluation of β-glucuronidase(s) from Escherichia coli or intestinal segments to release the head group.[2]

about recent application data generated by Sigma R&D to optimize hydrolysis for different drug classes using enzymes from different sources and the use of a chromatographicaly purified enzyme to reduce the effect of esterase activity resulting in conversion of 6-MAM to Morphine

Effective in the hydrolysis of steroid glucuronides.

Used for the hydrolysis of glucuronide conjugates in urinary metabolite analysis

Physical form

β-glucuronidase is used as a reporter gene in GUS assays to monitor gene expression.

Highly purified solution in 50% glycerol

Other Notes

One Sigma or modified Fishman unit will liberate 1.0 μg of phenolphthalein from phenolphthalein glucuronide per hr at 37 °C at the pH 6.8 (30 min assay).
