KEGG   ENZYME: 3.2.1.218
Entry
EC 3.2.1.218                Enzyme                                 
Name
alpha-3'-ketoglucosidase;
3'-keto-alpha-D-gluco-disaccharide hydrolase;
alpha-3-ketoglucosidase (incorrect);
3-keto-glucoside hydrolase
Class
Hydrolases;
Glycosylases;
Glycosidases, i.e. enzymes that hydrolyse O- and S-glycosyl compounds
Sysname
3'-dehydrosucrose 3'-dehydroglucohydrolase
Reaction(IUBMB)
3'-dehydrosucrose + H2O = 3-dehydro-D-glucopyranose + D-fructofuranose [RN:R13128]
Reaction(KEGG)
R13128
Substrate
3'-dehydrosucrose [CPD:C05731];
H2O [CPD:C00001]
Product
3-dehydro-D-glucopyranose [CPD:C22635];
D-fructofuranose
Comment
The enzyme, originally characterized from the bacterium Agrobacterium tumefaciens, is specific for disaccharides that contain a 3-dehydro-alpha-D-glucose at the non-reducing end such as 3'-dehydrosucrose and 3'-dehydro-alpha,alpha-trehalose. It has no activity with disaccharides in which the glucose is in beta conformation, and greatly reduced activity with disaccharides with an unmodified 3' position.
