Fructose 5 dehydrogenase (NADP )

In enzymology, a fructose 5-dehydrogenase (NADP⁺) (EC 1.1.1.124) is an enzyme that catalyzes the chemical reaction

Thus, the two substrates of this enzyme are D-fructose and NADP⁺, whereas its 3 products are 5-dehydro-D-fructose, 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-fructose:NADP⁺ 5-oxidoreductase. Other names in common use include 5-ketofructose reductase (NADP⁺), 5-keto-D-fructose reductase (NADP⁺), fructose 5-(nicotinamide adenine dinucleotide phosphate), dehydrogenase, D-(-)fructose:(NADP⁺) 5-oxidoreductase, and fructose 5-dehydrogenase (NADP⁺).
