DE   alpha-3'-ketoglucosidase.
AN   3'-keto-alpha-D-gluco-disaccharide hydrolase.
AN   3-keto-glucoside hydrolase.
CA   3'-dehydrosucrose + H2O = 3-dehydro-D-glucopyranose + beta-D-
CA   fructofuranose.
CC   -!- The enzyme, originally characterized from the bacterium Agrobacterium
CC       tumefaciens, is specific for disaccharides that contain a 3-dehydro-
CC       alpha-D-glucose at the non-reducing end such as 3'-dehydrosucrose and
CC       3'-dehydro-alpha,alpha-trehalose.
CC   -!- It has no activity with disaccharides in which the glucose is in beta
CC       conformation, and greatly reduced activity with disaccharides with an
CC       unmodified 3' position.
