Thus, the two substrates of this enzyme are 5,6-dihydrouracil and O2, whereas its two products are uracil and H2O2.
This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-CH group of donor with oxygen as acceptor. The systematic name of this enzyme class is 5,6-dihydrouracil:oxygen oxidoreductase. It employs one cofactor, FMN.
