Application
β-glucuronidase was used in enzymic hydrolysis of tissue homogenates for liquid chromatography-electrospray ion trap mass spectrometry (LC/MSn) analysis, to study the structures of degradation products of baicalin.
Biochem/physiol Actions
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.

The determination of a large number of three-dimensional structures of glycosidases, both free and in complex with ligands, has provided valuable new insights into glycosidase catalysis, especially when coupled with results from studies of specifically labelled glycosidases and kinetic analyses

The X-ray structure of the homotetrameric lysosomal acid hydrolase, human beta-glucuronidase (332,000 Mr), has been determined at 2.6 A resolution. The tetramer has approximate dihedral symmetry and each promoter consists of three structural domains with topologies similar to a jelly
