Project description:The diazotrophic bacterium Rhodobacter capsulatus is able to synthesize two nitrogenases, a molybdenum-dependent and an alternative Mo-free iron-only nitrogenase, enabling growth with molecular dinitrogen (N2) as sole nitrogen source. The Mo response of the wild type and a mutant lacking the high-affinity molybdate transporter, ModABC, were analyzed by proteome profiling.

Regulation of nitrogen fixation was analyzed by proteome profiling of wild-type and mutant strains lacking the transcriptional regulators NifA, AnfA, and MopAB.
