ENZYME entry: EC 3.2.1.194

Accepted Name
Ginsenosidase type IV.
Reaction catalysed
A protopanaxatriol-type ginsenoside with two glycosyl residues at position 6 + 2 H(2)O <=> a protopanaxatriol-type ginsenoside with no glycosidic modification at position 6 + D-glucopyranose + a monosaccharide
Comment(s)
Ginsenosidase type IV catalyzes the sequential hydrolysis of the 6-O- beta-D-(1->2)-glycosidic bond or the 6-O-alpha-D-(1->2)-glycosidic bond in protopanaxatriol-type ginsenosides with a disacchride attached to the C(6) position, followed by the hydrolysis of the remaining 6-O-beta-D-glycosidic bond (e.g. ginsenoside Re -> ginsenoside Rg1 -> ginsenoside F1).
