L-idonate 2-dehydrogenase

In enzymology, a L-idonate 2-dehydrogenase is an enzyme that catalyzes the chemical reaction


 * L-idonate + NADP+ $$\rightleftharpoons$$ 5-dehydro-D-gluconate + NADPH + H+

Thus, the two substrates of this enzyme are L-idonate and NADP+, whereas its 3 products are 5-dehydro-D-gluconate, 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 L-idonate:NADP+ 2-oxidoreductase. Other names in common use include 5-ketogluconate 2-reductase, 5-keto-D-gluconate 2-reductase, L-idonate dehydrogenase, 5-ketogluconate 2-reductase, reductase, 5-ketogluconate 5- (L-idonate-forming), 5KGR, and 5-ketoglucono-idono-reductase.
