Thus, the two substrates of this enzyme are catechol and O₂, whereas its two products are [[dibenzo[1,4]dioxin-2,3-dione]] and H₂O.

This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with oxygen as acceptor. The systematic name of this enzyme class is catechol:oxygen oxidoreductase (dimerizing).
