Accepted name: | baicalin-β-D-glucuronidase | ||||||||
Reaction: | baicalin + H2O = baicalein + D-glucuronate | ||||||||
Glossary: | baicalin = 5,6,7-trihydroxyflavone-7-O-β-D-glucuronate = 5,6-dihydroxy-4-oxo-2-phenyl-4H-chromen-7-yl β-D-glucupyranosiduronic acid baicalein = 5,6,7-trihydroxyflavone = 5,6,7-trihydroxy-2-phenyl-4H-chromen-4-one wogonin = 5,7-dihydroxy-8-methoxyflavone = 5,7-dihydroxy-8-methoxy-2-phenyl-4H-chromen-4-one oroxylin = 5,7-dihydroxy-6-methoxyflavone = 5,7-dihydroxy-6-methoxy-2-phenyl-4H-1-benzopyran-4-one |
||||||||
Other name(s): | baicalinase | ||||||||
Systematic name: | 5,6,7-trihydroxyflavone-7-O-β-D-glucupyranosiduronate glucuronosylhydrolase | ||||||||
Comments: | The enzyme also hydrolyses wogonin 7-O-β-D-glucuronide and oroxylin 7-O-β-D-glucuronide with lower efficiency [4]. Neglegible activity with p-nitrophenyl-β-D-glucuronide [2]. | ||||||||
