Reaction: hesperidin + H2O = hesperitin + rutinose
Glossary: hesperitin = 5,7,3'-trihydroxy-4'-methoxyflavanone
hesperidin = hesperitin 7-(6-O-α-L-rhamnopyranosyl-β-D-glucopyranoside)
rutinose = 6-O-α-L-rhamnopyranosyl-D-glucose
Other name(s): AnRut; rutinosidase
Systematic name: hesperetin 7-(6-O-α-L-rhamnopyranosyl-β-D-glucopyranoside) 6-O-α-rhamnopyranosyl-β-glucohydrolase
Comments: The enzyme exhibits high specificity towards 7-O-linked flavonoid β-rutinosides.
