ID 1.1.99.13 DE glucoside 3-dehydrogenase (acceptor). AN D-aldohexopyranoside dehydrogenase. AN D-glucoside 3-dehydrogenase. CA A + sucrose = 3-dehydro-alpha-D-glucosyl beta-D-fructofuranoside + AH2. CC -!- The enzymes from members of the Rhizobiaceae family (such as CC Agrobacterium tumefaciens) act on disaccharides that contain a CC glucose moiety at the non-reducing end, such as sucrose, trehalose, CC leucrose, palatinose, trehalulose, and maltitol, forming the CC respective 3'-keto derivatives. cf. EC 1.1.2.11. //
