In enzymology, a gluconate 5-dehydrogenase (EC 1.1.1.69) is an enzyme that catalyzes the chemical reaction
- D-gluconate + NAD(P)+ 5-dehydro-D-gluconate + NAD(P)H + H+
The 3 substrates of this enzyme are D-gluconate, NAD+, and NADP+, whereas its 4 products are 5-dehydro-D-gluconate, NADH, NADPH, 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 D-gluconate:NAD(P)+ 5-oxidoreductase. Other names in common use include 5-keto-D-gluconate 5-reductase, 5-keto-D-gluconate 5-reductase, 5-ketogluconate 5-reductase, 5-ketogluconate reductase, and 5-keto-D-gluconate reductase.
Structural studies[edit]
As of late 2007, only one structure has been solved for this class of enzymes, with the PDB accession code 1VL8.
