Genome reduction in the α-Proteobacteria
Current Opinion in Microbiology, 2005More than 20 alpha-proteobacterial genomes are currently available. These range in size from 1-9 Mb and represent excellent model systems for evolutionary studies of the organizational features of bacterial genomes. Computational inferences have shown that genome reductions have occurred independently in lineages such as Rickettsia and Bartonella that ...

IBD—what role do Proteobacteria play?
Nature Reviews Gastroenterology & Hepatology, 2012The gastrointestinal microbiota has come to the fore in the search for the causes of IBD. This shift has largely been driven by the finding of genetic polymorphisms involved in gastrointestinal innate immunity (particularly polymorphisms in NOD2 and genes involved in autophagy) and alterations in the composition of the microbiota that might result in ...

Morphological and functional asymmetry in α-proteobacteria
Trends in Microbiology, 2004The release of an increasing number of complete bacterial genomic sequences allows the evolutionary analysis of processes such as regulatory networks. CtrA is a response regulator of the OmpR subfamily, belonging to a complex regulatory network in the dimorphic bacterium Caulobacter crescentus. It coordinates the cell cycle with an asymmetric division,

Succinate:quinone oxidoreductases from epsilon-proteobacteria.
Biochimica et biophysica acta, 2002The epsilon-proteobacteria form a subdivision of the Proteobacteria including the genera Wolinella, Campylobacter, Helicobacter, Sulfurospirillum, Arcobacter and Dehalospirillum. The majority of these bacteria are oxidase-positive microaerophiles indicating an electron transport chain with molecular oxygen as terminal electron acceptor.

Genomic comparisons among γ‐proteobacteria
Environmental Microbiology, 2005Summary Predicted highly expressed (PHX) genes are compared for 16 γ‐proteobacteria and their similarities and differences are interpreted with respect to known or predicted physiological characteristics of the organisms. Predicted highly expressed genes often reflect the organism's predominant lifestyle, habitat,

Aciduric Proteobacteria isolated from pH 2.9 soil
Archives of Microbiology, 2002Acidic (pH 2.9) soil was used as an inoculum to culture heterotrophic bacteria at pH values of 3-4. Four isolates were obtained; on the basis of 16S rDNA sequence, they were shown to be members of the beta- and gamma-Proteobacteria. The three isolates that were most closely related to Burkholderia spp. had simple nutritional requirements and could grow

Genomic comparisons among gamma-proteobacteria.
Environmental microbiology, 2006Predicted highly expressed (PHX) genes are compared for 16 gamma-proteobacteria and their similarities and differences are interpreted with respect to known or predicted physiological characteristics of the organisms. Predicted highly expressed genes often reflect the organism's predominant lifestyle, habitat, nutrition sources and metabolic ...
