ENZYME entry: EC 3.2.1.189
| Accepted Name |
|---|
| dioscin glycosidase (diosgenin-forming).
|
| Alternative Name(s) |
|---|
| dioscin glycosidase (aglycone-forming). |
| Reaction catalysed |
|---|
| dioscin + 3 H2O <=> D-glucose + diosgenin + 2 L-rhamnopyranose |
| Comment(s) |
|---|
- 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.
- (cf. EC 3.2.1.190).
