DE   ginsenosidase type I.
CA   (1) a protopanaxadiol-type ginsenoside with two glucosyl residues at
CA   position 3 + H2O = a protopanaxadiol-type ginsenoside with one glucosyl
CA   residue at position 3 + D-glucopyranose.
CA   (2) a protopanaxadiol-type ginsenoside with one glucosyl residue at
CA   position 3 + H2O = a protopanaxadiol-type ginsenoside with no glycosidic
CA   modifications at position 3 + D-glucopyranose.
CA   (3) a protopanaxadiol-type ginsenoside with two glycosyl residues at
CA   position 20 + H2O = a protopanaxadiol-type ginsenoside with a single
CA   glucosyl residue at position 20 + a monosaccharide.
CC   -!- The enzyme hydrolyzes the 3-O-beta-D-(1->2)-glucosidic bond, the 3-O-
CC       beta-D-glucopyranosyl bond and the 20-O-beta-D-(1->6)-glycosidic bond
CC       of protopanaxadiol-type ginsenosides.
CC   -!- It usually leaves a single glucosyl residue attached at position 20
CC       and one or no glucosyl residues at position 3.
CC   -!- Starting with a ginsenoside that is glycosylated at both positions
CC       (e.g. ginsenoside Rb1, Rb2, Rb3, Rc or Rd), the most common products
CC       are ginsenoside F2 and ginsenoside C-K, with low amounts of
CC       ginsenoside Rh2.
