Abstract: The effect of exposure to carbon monoxide on the activity of the (Fe) hydrogenase from Desulfovibrio vulgaris has been determined. Concentrations of carbon monoxide which completely inhibit hydrogenase activity and induce formation of the axial g =2.06 EPR signal up to 0.8 spin/molecule do not cause irreversible inhibition of the (Fe) hydrogenase.
