ENZYME entry: EC 3.2.1.189
| 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 |
| 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).
