EC 1.1.1.127

Accepted name: 2-dehydro-3-deoxy-D-gluconate 5-dehydrogenase

Reaction: 2-dehydro-3-deoxy-D-gluconate + NAD+ = (4S)-4,6-dihydroxy-2,5-dioxohexanoate + NADH + H+

Other name(s): 2-keto-3-deoxygluconate 5-dehydrogenase; 2-keto-3-deoxy-D-gluconate dehydrogenase; 2-keto-3-deoxygluconate (nicotinamide adenine dinucleotide (phosphate)) dehydrogenase; 2-keto-3-deoxy-D-gluconate (3-deoxy-D-glycero-2,5-hexodiulosonic acid) dehydrogenase

Systematic name: 2-dehydro-3-deoxy-D-gluconate:NAD+ 5-oxidoreductase

Comments: The enzyme from Pseudomonas acts equally well on NAD+ or NADP+, while that from Erwinia chrysanthemi and Escherichia coli is more specific for NAD+.
