Thus, the two substrates of this enzyme are 5,12-dihydroxanthommatin and NAD+, whereas its three products are xanthommatin, NADH, and H+.

This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-CH group of donor with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is 5,12-dihydroxanthommatin:NAD+ oxidoreductase.
