Baicalin-beta-D-glucuronidase (EC 3.2.1.167, baicalinase) is an enzyme with systematic name 5,6,7-trihydroxyflavone-7-O-beta-D-glucupyranosiduronate glucuronosylhydrolase.[1][2][3][4] This enzyme catalyses the following chemical reaction
- baicalin + H2O baicalein + D-glucuronate
The enzyme also hydrolyses wogonin 7-O-beta-D-glucuronide and oroxylin 7-O-beta-D-glucuronide with lower efficiency.
