In enzymology, a mannitol dehydrogenase (cytochrome) (EC 1.1.2.2) is an enzyme that catalyzes the chemical reaction Thus, the two substrates of this enzyme are D-mannitol and ferricytochrome c, whereas its two products are D-fructose and ferrocytochrome c. This enzyme belongs to the family of oxidoreductases, to be specific those acting on the CH-OH group of donor with a cytochrome as acceptor.
The systematic name of this enzyme class is D-mannitol:ferricytochrome-c 2-oxidoreductase.
This enzyme is also called polyol dehydrogenase.
This enzyme participates in pentose and glucuronate interconversions and fructose and mannose metabolism
