摘要: The iron-molybdenum cofactor isolated from component I of nitrogenase catalyzes the reduction of acetylene to ethylene in the presence of sodium borohydride. Like nitrogenase, this activity is strongly inhibited by carbon monoxide. From the initial rates of the reaction, the specific activity of the iron-molybdenum cofactor is 34 nmoles of ethylene formed per minute per nmole of Mo in the cofactor. This activity is about 8% of the activity of nitrogenase with an equivalent amount of Mo. ATP has no stimulatory effect on the cofactor activity.
