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).
