Rhodobacter capsulatus fixes atmospheric nitrogen (N<sub>2</sub> ) by a molybdenum (Mo)-nitrogenase and a Mo-free iron (Fe)-nitrogenase, whose production is induced or repressed by Mo, respectively. At low nanomolar Mo concentrations, both isoenzymes are synthesized and contribute to nitrogen fixation. Here we examined the regulatory interplay of the central transcriptional activators NifA and AnfA by proteome profiling. As expected from earlier studies, synthesis of the structural proteins of M ...[more]
