CSF26G1;
furostanol glycoside 26-O-beta-D-glucosidase;
furostanol 26-O-beta-D-glucoside glucohydrolase
Class
Hydrolases;
Glycosylases;
Glycosidases, i.e. enzymes that hydrolyse O- and S-glycosyl compounds
Sysname
protodioscin glucohydrolase
Reaction(IUBMB)
protodioscin + H2O = 26-deglucoprotodioscin + D-glucose [RN:R10530]
Reaction(KEGG)
R10530
Substrate
protodioscin [CPD:C08907];
H2O [CPD:C00001]
Product
26-deglucoprotodioscin [CPD:C20678];
D-glucose [CPD:C00031]
Comment
The enzyme has been characterized from the plants Cheilocostus speciosus and Solanum torvum. It also hydrolyses the 26-beta-D-glucose group from related steroid glucosides such as protogracillin, torvoside A and torvoside H.
