In enzymology, fructuronate reductase (EC 1.1.1.57) is an enzyme that catalyzes the chemical reaction

D-mannonic acid
 
 
 
H+
 
H+
 
keto-D-fructuronic acid
 

The two substrates of this enzyme are D-mannonic acid and oxidised nicotinamide adenine dinucleotide (NAD+). Its products are D-fructuronic acid (shown in its keto form), reduced NADH, and a proton.

This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is D-mannonate:NAD+ 5-oxidoreductase. Other names in common use include mannonate oxidoreductase, mannonic dehydrogenase, D-mannonate dehydrogenase, and D-mannonate:NAD+ oxidoreductase. This enzyme participates in pentose and glucuronate interconversions.
