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