H+
 
3-dehydro-L-threonic acid
 

The two substrates of this enzyme are threonic acid and oxidised nicotinamide adenine dinucleotide (NAD+). Its products are 3-dehydro-L-threonic acid, reduced NADH, and a proton.[1][2]

This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donors with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is L-threonate:NAD+ 3-oxidoreductase. Other names in common use include threonate dehydrogenase, and L-threonic acid dehydrogenase. This enzyme participates in ascorbate and aldarate metabolism.
