 Acireductone dioxygenase (Ni2+-requiring)

Acireductone dioxygenase (Ni2+-requiring) () is an enzyme that catalyzes the chemical reaction

Thus, the two substrates of this enzyme are 1,2-dihydroxy-5-(methylthio)pent-1-en-3-one and oxygen, whereas its 3 products are 3-(methylthio)propanoate, formate, and carbon monoxide.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).
