We follow the initial activation of the nitrogen molecule at the FeMo cofactor of nitrogenase and subsequently model the hydrogenation of N up to the fourth 2 protonation step using the intermediate neglect of differential overlap quantum-chemical model. The results obtained favor a reaction mechani
Nitrogenase of Azotobacter vindandii is sensitive to oxygen, and sensitivity develops during purification. Such inactivation is well prevented by 0.1% hydroquinone plus 0.01 ~ ascorbate, which are also effective in preventing inactivation of enzyme on storage under H2. Activity is proportional to fe
