Nitrogenases without molybdenum.


For 50 years molybdenum had been considered to have an indispensable catalytic function for nitrogen fixation. Two nitrogenases recently isolated from the bacterium Azotobacter have changed this view. One is a vanadium-containing enzyme and the other lacks both molybdenum and vanadium. Similar nitrogenases may occur in other nitrogen-fixing organisms.
