In enzymology, L-idonate 5-dehydrogenase (EC 1.1.1.264) is an enzyme that catalyzes the chemical reaction

L-idonate 5-dehydrogenase
 
H+
 
+ NADH
 

The two substrates of this enzyme are L-idonic acid and oxidised nicotinamide adenine dinucleotide (NAD+). Its products are 5-oxo-D-gluconic acid, 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 L-idonate:NAD(P)+ oxidoreductase.
