Abstract excerpt
Nitrogenase activity is regulated by reversible ADP-ribosylation in response to NH4+ and anaerobic conditions in Azospirillum brasilense. The effect of mutations in ntrBC on this regulation was examined. While NH4+ addition to ntrBC mutants caused a partial loss of nitrogenase activity, the effec...
