Thus, the two substrates of this enzyme are 1,5-anhydro-D-mannitol and NADP⁺, whereas its 3 products are 1,5-anhydro-D-fructose, NADPH, and H⁺.

This enzyme belongs to the common 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 1,5-anhydro-D-mannitol:NADP⁺ oxidoreductase. Other names in common use include 1,5-anhydro-D-fructose reductase (ambiguous), and AFR.
