ENZYME entry: EC

Accepted Name
Dioscin glycosidase (diosgenin-forming).
Alternative Name(s)
Dioscin glycosidase (aglycone-forming).
Reaction catalysed
3-O-[alpha-L-Rha-(1->4)-(alpha-L-Rha-(1->2))-beta-D-Glc]diosgenin + 3 H(2)O <=> D-glucose + 2 L-rhamnose + diosgenin
  • The enzyme is involved in degradation of the steroid saponin dioscin by some fungi of the Absidia genus.
  • The enzyme can also hydrolyze 3-O-[alpha-L-Ara-(1->4)-(alpha-L-Rha- (1->2))-beta-D-Glc]diosgenin into diosgenin and free sugars as the final products.
