Reaction: glycyrrhizinate + H2O = (1→2)-β-D-glucuronosyl-D-glucuronate + glycyrrhetinate
Other name(s): glycyrrhizin β-hydrolase; glycyrrhizin hydrolase; glycyrrhizinic acid hydrolase
Systematic name: glycyrrhizinate glucuronosylhydrolase
Comments: The enzyme from Aspergillus niger is specific for the hydrolysis of the triterpenoid glycoside glycyrrhizinate from roots of Glycyrrhiza sp.
