Thus, the two substrates of this enzyme are erythritol and NADP⁺, whereas its 3 products are D-erythrulose, 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 erythritol:NADP⁺ oxidoreductase. This enzyme is also called D-erythrulose reductase.
