Proteome profiling of Rhodobacter capsulatus wild type and a ΔmodABC mutant in response to molybdenum

ABSTRACT: 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.

Rhodobacter capsulatus is capable of synthesizing two nitrogenases, a molybdenum-dependent nitrogenase and an alternative Mo-free iron-only nitrogenase, enabling this diazotroph to grow with molecular dinitrogen (N2) as the sole nitrogen source. Here, the Mo responses of the wild type and of a mutant lacking ModABC, the high-affinity molybdate transporter, were examined by proteome profiling, Western analysis, epitope tagging, and lacZ reporter fusions. Many Mo-controlled proteins identified in  ...[more]
