EC 1.1.5.14     
Accepted name: fructose 5-dehydrogenase
Reaction: D-fructose + a ubiquinone = 5-dehydro-D-fructose + a ubiquinol
Other name(s): fructose 5-dehydrogenase (acceptor); D-fructose dehydrogenase; D-fructose:(acceptor) 5-oxidoreductase
Systematic name: D-fructose:ubiquinone 5-oxidoreductase
Comments: The enzyme, characterized from the bacterium Gluconobacter japonicus, is a heterotrimer composed of an FAD-containing large subunit, a small subunit, and a heme c-containing subunit, which is responsible for anchoring the complex to the cytoplasmic membrane and for transferring the electrons to ubiquinone.
