Abstract

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 P(II) modification is dependent on the nitrogen source used for growth, N(2) or glutamate, although both lead to nitrogenase derepression.
