TranscriptomicsFunctional genomic analysis of three nitrogenase isozymes in the photosynthetic bacterium Rhodopseudomonas palustris
To address the question of how photosynthetic bacterium Rhodopseudomonas palustris differentially regulates gene expression of three nitrogenase isozymes (Mo, V, and Fe nitrogenases), we constructed Mo strain (Mo nitrogenase only strain), V strain (V nitrogenase only strain), and Fe strain (Fe nitro...

TranscriptomicsHow post-translational modification of nitrogenase is circumvented in Rhodopseudomonas palustris strains that produce hydrogen gas constitutively
Characterization of post-translational modification of nitrogenase in Rhodopseudomonas palustris strains that produce hydrogen gas constitutively. To characterize the effect of yeast extract as nitrogen source on gene expression under nitrogen fixing conditions, expression profiles of wild-type cell...

ProteomicsNot just an alternative nitrogenase: The Fe-nitrogenase system belongs to the NifA regulon in Rhodobacter capsulatus
The diazotrophic bacterium Rhodobacter capsulatus synthesizes a molybdenum nitrogenase and an alternative iron-only nitrogenase, enabling growth with molecular dinitrogen as sole nitrogen source. Regulation of nitrogen fixation was analyzed by proteome profiling of wild-type and mutant strains lacki...

ProteomicsTwo distinct ferredoxins are essential for nitrogen fixation by the iron nitrogenase in Rhodobacter capsulatus
Nitrogenases are the only enzymes able to ‘fix’ gaseous nitrogen into bioavailable ammonia and, hence, are essential for sustaining life. Catalysis by nitrogenases requires both a large amount of ATP and electrons donated by strongly reducing ferredoxins or flavodoxins. Our knowledge about the mecha...

TranscriptomicsA hybrid nitrogenase with regulatory elasticity in Azotobacter vinelandii
Biological nitrogen fixation, the microbial reduction of atmospheric nitrogen to bioavailable ammonia, represents both a major limitation on biological productivity and a highly desirable engineering target for synthetic biology. However, the engineering of nitrogen fixation requires an integrated u...

TranscriptomicsRedirection of metabolism for biological hydrogen production
Photosynthetic microbes can produce the clean-burning fuel hydrogen using one of natureâ??s most plentiful resources, sunlight 1,2. Anoxygenic photosynthetic bacteria generate hydrogen and ammonia during a process known as biological nitrogen fixation. This reaction is catalyzed by the enzyme nitrog...

TranscriptomicsRNAseq data for Nitrogenase regulation in Vibrio natriegens differs from other γ-proteobacteria
Regulation of nitrogenase, which converts nitrogen gas (N2) into ammonium (NH4+), typically involves a conserved set of regulatory proteins across diverse N2-fixing (diazotrophic) bacteria. However, the interactions and relative influence of these regulators can vary between species. Thus, one canno...
