1.18.6.1 additional information reduction of nitrogenase activity in cells overexpressing PII protein participating in nif regulation is due to partial ADP-ribosylation of the Fe-protein under derepressing conditions and a reduction in the amount of Fe-protein. In cells overexpressing the PZ protein which negatively regulates ammonium transport the nitrogenase reactivation after an ammonium shock is delayed Azospirillum brasilense
