Function
function
Polyol dehydrogenase that catalyzes the reversible NAD+-dependent oxidation of various sugar alcohols. Is active with D-sorbitol (D-glucitol) leading to the C2-oxidized product D-fructose. Is a key enzyme in the polyol pathway that interconverts glucose and fructose via sorbitol, which constitutes an important alternate route for glucose metabolism. May play a role in sperm motility by using sorbitol as an alternative energy source for sperm motility.
Catalytic activity
- keto-D-fructose + NADH + H+ = D-sorbitol + NAD+
Cofactor
Note: Binds 1 or 2 Zn2+ ions per subunit.
