Accepted name: |
glucoside 3-dehydrogenase (acceptor) |
Reaction: |
sucrose + acceptor = 3-dehydro-α-D-glucosyl-β-D-fructofuranoside + reduced acceptor |
Other name(s): |
D-glucoside 3-dehydrogenase (ambiguous); D-aldohexopyranoside dehydrogenase (ambiguous); D-aldohexoside:(acceptor) 3-oxidoreductase; thuA (gene name); thuB (gene name); glucoside 3-dehydrogenase |
Systematic name: |
D-aldohexoside:acceptor 3-oxidoreductase |
Comments: |
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). |
