Protein attributes

Sequence length	253 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

General annotation (Comments)

Function	Catalyzes the reduction of 2,5-diketo-3-deoxygluconate (DKII or 4,6-dihydroxy-2,5-dioxohexanoate) into 2-keto-3-deoxygluconate (KDG or 2-dehydro-3-deoxygluconate) with a concomitant oxidation of NADH By similarity.
Catalytic activity	2-dehydro-3-deoxy-D-gluconate + NAD+ = (4S)-4,6-dihydroxy-2,5-dioxohexanoate + NADH.
Sequence similarities	Belongs to the short-chain dehydrogenases/reductases (SDR) family.
