TranscriptomicsEffects of the Fnr homologue AadR on global gene expression
In order to define the AadR regulon we did transcriptome analysis of an aadR in frame-deletion mutant and compared to that of wild type. We found that AadR positively modulated expression of 43 genes, most of which are involved in degradation of aromatic acids under anaerobic conditions. It also act...

TranscriptomicsFixK, a universal regulator of microaerobic growth, controls photosynthesis in Rhodopseudomonas palustris
Facultative phototrophic bacteria are excellent models for analyzing the coordination of major metabolic traits including oxidative phosphorylation, photophosphorylation, carbon dioxide fixation and nitrogen fixation. In Rhodobacter sphaeroides and R. capsulatus, a two-component system called RegBA ...

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...

TranscriptomicsThe activity of Rhodopseudomonas palustris p-coumaroyl-homoserine lactone-responsive transcription factor RpaR
The Rhodopseudomonas palustris transcriptional regulator RpaR responds to the RpaI-synthesized quorum-sensing signal p-coumaroyl-homoserine lactone (pC-HSL). Other characterized RpaR homologs respond to fatty acyl-HSLs. We show here that RpaR functions as a transcriptional activator, which binds dir...

ProteomicsCsrA-controlled proteins important for Acinetobacter baumannii desiccation tolerance
Hospital environments serve as excellent reservoirs for the opportunistic pathogen Acinetobacter baumannii in part because it is exceptionally tolerant to desiccation. To understand the functional basis this trait, we used transposon sequencing (Tn-seq) to identify genes contributing to desiccatio...

TranscriptomicsA New Class of Homoserine Lactone Quorum Sensing Signals
Quorum sensing is a term used to describe cell-to-cell communication that allows cell density-dependent gene expression. Many Gram-negative bacteria use acyl-homoserine lactone (acyl-HSL) synthases to generate fatty acyl-HSL quorum sensing signals, which function with signal receptors to control exp...
