Overview

β-Glucuronidase from Escherichia coli is similar to human glucuronidase enzyme and corresponds to molecular weight close to 69-71 kDa and has an pH optimum of 6.5-7.5. It belongs to family-2 glycosyl hydrolase and has active site residues glutamic acid 394, tyrosine 468 and glutamic acid 504.

Application:

β-Glucuronidase from Escherichia coli has been used in the enzymatic cleavage and activation of glucuronide prodrugs in non-small cell lung cancer cells, U87 human glioblastoma cell line, in A549 (human lung adenocarcinoma) and KB (human oral squamous carcinoma).

β-Glucuronidase from E. coli is used for the enzymatic hydrolysis of b-glucuronides in urine and other fluids. It has a high rate of hydrolytic activity and may be useful for determining the presence of androsterone, 17-hydroxycorticosteroids, and estriol in urine.
The optimal conditions for the enzymatic hydrolysis of α-hydroxytriazolam, one of the major metabolites of triazolam in human urine, were determined using β-glucuronidase Type IX-A.
It is used as a reporter gene in GUS assays to monitor gene expression.
