EC 3.2.1.168     
Accepted name: hesperidin 6-O-α-L-rhamnosyl-β-D-glucosidase
Reaction: hesperidin + H2O = hesperetin + rutinose
Glossary: hesperetin = 5,7,3′-trihydroxy-4′-methoxyflavanone
hesperidin = hesperetin 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.
