ENZYME entry: EC 3.2.1.191

Accepted Name
Ginsenosidase type III.
Reaction catalysed
A protopanaxadiol-type ginsenoside with two glucosyl residues at position 3 + 2 H(2)O <=> a protopanaxadiol-type ginsenoside with no glycosidic modification at position 3 + 2 D-glucopyranose
Comment(s)
  • Ginsenosidase type III catalyzes the sequential hydrolysis of the 3-O-beta-D-(1->2)-glucopyranosyl bond followed by hydrolysis of the 3-O-beta-D-glucopyranosyl bond of protopanaxadiol ginsenosides.
  • When acting for example on ginsenoside Rb1 the enzyme first generates ginsenoside XVII, and subsequently ginsenoside LXXV.
