Comment
The enzymes from members of the Rhizobiaceae family (such as Agrobacterium tumefaciens) act on disaccharides that contain a glucose moiety at the non-reducing end, such as sucrose, trehalose, leucrose, palatinose, trehalulose, and maltitol, forming the respective 3'-keto derivatives. cf. EC 1.1.2.11, glucoside 3-dehydrogenase (cytochrome c).
