ENZYME entry: EC

Accepted Name
20-O-multi-glycoside ginsenosidase
Reaction catalysed
a protopanaxadiol-type ginsenoside with two glycosyl residues at position 20 + H2O <=> a protopanaxadiol-type ginsenoside with a single glucosyl residue at position 20 + a monosaccharide
  • The 20-O-multi-glycoside ginsenosidase catalyzes the hydrolysis of the 20-O-alpha-(1->6)-glycosidic bond and the 20-O-beta-(1->6)- glycosidic bond of protopanaxadiol-type ginsenosides.
  • The enzyme usually leaves a single glucosyl residue attached at position 20, although it can cleave the remaining glucosyl residue with a lower efficiency.
  • Starting with a ginsenoside that is glycosylated at positions 3 and 20, such as ginsenosides Rb1, Rb2, Rb3 and Rc, the most common product is ginsenoside Rd, with a low amount of ginsenoside Rg3 also formed.
