The two substrates of this enzyme are 3,3'-dimethoxy-trans-stilbene-4,4'-diol and oxygen. Its product is two equivalents of vanillin. The enzyme from Pseudomonas species cleaves the ethylene bond in a general class of natural lignin derivatives called lignostilbenes.[1][2]
This enzyme belongs to the family of oxidoreductases, specifically those acting on single donors with O2 as oxidant and incorporation of two atoms of oxygen into the substrate (oxygenases). The oxygen incorporated need not be derived from O2. The systematic name of this enzyme class is 1,2-bis(4-hydroxy-3-methoxyphenyl)ethylene:oxygen oxidoreductase (alphabeta-bond-cleaving). It employs one cofactor, iron.
