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.
