Accepted name: hesperidin 6-O-α-L-rhamnosyl-β-D-glucosidase

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

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.
