In enzymology, mannuronate reductase (EC 1.1.1.131) is an enzyme that catalyzes the chemical reaction

+ NAD+
 
 
 
H+
Mannuronate reductase
 
H+
 
+ NADH
 

The two substrates of this enzyme are D-mannonic acid and oxidised nicotinamide adenine dinucleotide (NAD+). Its products are D-mannuronic acid (shown in open-chain form), reduced NADH, and a proton. The enzyme can also use the alternative cofactor, nicotinamide adenine dinucleotide phosphate. [1] [2]

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(P)+ 6-oxidoreductase. Other names in common use include mannonate dehydrogenase, mannonate (nicotinamide adenine dinucleotide, (phosphate))dehydrogenase, mannonate dehydrogenase, mannuronate reductase, mannonate dehydrogenase (NAD(P)+), D-mannonate:nicotinamide adenine dinucleotide (phosphate, and oxidoreductase (D-mannuronate-forming)).
