Abstract excerpt
Azospirillum brasilense NifA, which is synthesized under all physiological conditions, exists in an active or inactive from depending on the availability of ammonia. The activity also depends on the presence of PII, as NifA is inactive in a glnB mutant. To investigate further the mechanism that r...
