The two substrates of this enzyme are 2-dehydro-3-deoxy-D-gluconic acid and oxidised nicotinamide adenine dinucleotide phosphate (NADP+). Its products are (4S,5S)-4,5-dihydroxy-2,6-dioxohexanoic acid, reduced NADPH, and a proton. [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 2-dehydro-3-deoxy-D-gluconate:NADP+ 6-oxidoreductase. Other names in common use include 2-keto-3-deoxy-D-gluconate dehydrogenase, and 2-keto-3-deoxygluconate dehydrogenase.
