Comments
Ginsenosidase type III catalyses the sequential hydrolysis of the 3-O-¦Â-D-(1¡ú2)-glucopyranosyl bond followed by hydrolysis of the 3-O-¦Â-D-glucopyranosyl bond of protopanaxadiol ginsenosides. When acting for example on ginsenoside Rb1 the enzyme first generates ginsenoside XVII, and subsequently ginsenoside LXXV.
Cofactor
