Description
Ginsenosidase type I is slightly activated by Mg2+ or Ca2+. The enzyme hydrolyses the 3-O-β-D-(1→2)-glucosidic bond, the 3-O-β-D-glucopyranosyl bond and the 20-O-β-D-(1→6)-glycosidic bond of protopanaxadiol-type ginsenosides. It usually leaves a single glucosyl residue attached at position 20 and one or no glucosyl residues at position 3. Starting with a ginsenoside that is glycosylated at both positions (e.g. ginsenoside Rb1, Rb2, Rb3, Rc or Rd), the most common products are ginsenoside F2 and ginsenoside C-K, with low amounts of ginsenoside Rh2.
Form
Liquid or lyophilized powder
Storage
Store it at +4 ºC for short term. For long term storage, store it at -20 ºC～-80 ºC.
Reaction
(1) a protopanaxadiol-type ginsenoside with two glucosyl residues at position 3 + H2O = a protopanaxadiol-type ginsenoside with one glucosyl residue at position 3 + D-glucopyranose; (2) a protopanaxadiol-type ginsenoside with one glucosyl residue at position 3 + H2O = a protopanaxadiol-type ginsenoside with no glycosidic modifications at position 3 + D-glucopyranose; (3) 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
