Thus, the two substrates of this enzyme are 2-deoxy-D-gluconate and NAD⁺, whereas its 3 products are 3-dehydro-2-deoxy-D-gluconate, NADH, and H⁺.

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-deoxy-D-gluconate:NAD⁺ 3-oxidoreductase. This enzyme is also called 2-deoxygluconate dehydrogenase. This enzyme participates in pentose and glucuronate interconversions.
