Glycyrrhizinate beta glucuronidase

In enzymology, a glycyrrhizinate beta-glucuronidase (EC 3.2.1.128) is an enzyme that catalyzes the chemical reaction

Thus, the two substrates of this enzyme are glycyrrhizinate and H₂O, whereas its two products are 1,2-beta-D-glucuronosyl-D-glucuronate and glycyrrhetinate.

This enzyme belongs to the family of hydrolases, to be specific those glycosidases that hydrolyse O- and S-glycosyl compounds. The systematic name of this enzyme class is glycyrrhizinate glucuronosylhydrolase. Other names in common use include glycyrrhizin beta-hydrolase, glycyrrhizin hydrolase, and glycyrrhizinic acid hydrolase.
