Nitrogenase switch-off and regulation of ammonium assimilation in response to light deprivation in Rhodospirillum rubrum are influnced by the nitrogen source used during growth

Nitrogen fixation and ammonium assimilation in Rhodospirillum rubrum are regulated in response to changes in light availability, and we show that the response in terms of glutamine synthetase activity and PII modification is dependent on the nitrogen source used for growth, N2 or glutamate, although both lead to nitrogenase derepression.
