Control of Azospirillum brasilense NifA activity by P II : effect of replacing Tyr residues of the NifA N-terminal domain on NifA activity

Abstract : It was previously reported that the N-terminal domain of Azospirillum brasilense NifA was a negative regulator of the NifA activity and that the PII protein prevented this inhibition under nitrogen fixing conditions. Here, we show that a mutation of a single Tyr residue at position 18 of the N-terminal domain of NifA led to an active NifA protein that did not require PII for activation under nitrogen fixation conditions.
