- L-idonate + NAD(P)+ 5-dehydrogluconate + NAD(P)H + H+
The 3 substrates of this enzyme are L-idonate, NAD+, and NADP+, whereas its 4 products are 5-dehydrogluconate, 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 L-idonate:NAD(P)+ oxidoreductase.
