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
## Abstract Azotobacter vinelandii __is a diazotrophic bacterium characterized by the outstanding capability of storing Mo in a special storage protein, which guarantees Mo‐dependent nitrogen fixation even under growth conditions of extreme Mo starvation. The Mo storage protein is constitutively sy
