1.13.11.53	dioxygenation	-	662091	
1.13.11.53	oxidation	ARD (Ni) converts aci-reductone to 3-(methylthio)propanoate, carbon monoxide, and formate, and the reaction is not part of the methionine salvage pathway cycle (off-pathway).	673849	
1.13.11.53	oxidation	if Ni+2 is bound in the active site, the substrate acireductone reacts with O2 to yield formate and 4-methylthio-2-ketobutyrate	675408
