The dependence of the rate of formation of ethylene on the concentration of an ethylene-forming enzyme was determined with a purified preparation of the ethylene-forming enzyme from Penicillium diglitatum IFO 9372. The relationship was not linear. When catalase and bovine serum albumin were added to the reaction mixture, the rate of formation of ethylene was directly proportional to the concentration of the enzyme. The non-linearity of the reaction, in the absence of these additives, is probably due to the hydroxyl radical ions (OH^・) produced by the Fenton reaction which occurs in the reaction mixture when ferrous ions and oxygen are present together under reducing conditions.
