The iron-oxidizing proteobacteria [PDF]
Microbiology, 2011 The ‘iron bacteria’ are a collection of morphologically and phylogenetically heterogeneous prokaryotes. They include some of the first micro-organisms to be observed and described, and continue to be the subject of a considerable body of fundamental and applied microbiological research.

Motility in the epsilon-proteobacteria [PDF]
Current Opinion in Microbiology, 2015 The epsilon-proteobacteria are a widespread group of flagellated bacteria frequently associated with either animal digestive tracts or hydrothermal vents, with well-studied examples in the human pathogens of Helicobacter and Campylobacter genera. Flagellated motility is important to both pathogens and hydrothermal vent members, and a number of curious ...

Proteobacteria: A Common Factor in Human Diseases [PDF]
BioMed Research International, 2017 Microbiota represents the entire microbial community present in the gut host. It serves several functions establishing a mutualistic relation with the host. Latest years have seen a burst in the number of studies focusing on this topic, in particular on intestinal diseases. In this scenario, Proteobacteria are one of the most abundant phyla, comprising

Evolution of Chi motifs in Proteobacteria [PDF]
G3 Genes|Genomes|Genetics, 2020 Abstract Homologous recombination is a key pathway found in nearly all bacterial taxa. The recombination complex allows bacteria to repair DNA double strand breaks but also promotes adaption through the exchange of DNA between cells.

Riboregulation in plant-associated α-proteobacteria [PDF]
RNA Biology, 2014 The symbiotic α-rhizobia Sinorhizobium meliloti, Bradyrhizobium japonicum, Rhizobium etli and the related plant pathogen Agrobacterium tumefaciens are important model organisms for studying plant-microbe interactions. These metabolically versatile soil bacteria are characterized by complex lifestyles and large genomes.

Morphological and functional asymmetry in α-proteobacteria
Trends in Microbiology, 2004 The 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,

Signature proteins that are distinctive of alpha proteobacteria [PDF]
BMC Genomics, 2005 Abstract Background The alpha (α) proteobacteria, a very large and diverse group, are presently characterized solely on the basis of 16S rRNA trees, with no known molecular characteristic that is unique to this group.

The dif/Xer Recombination Systems in Proteobacteria
PLoS ONE, 2009 In E. coli, 10 to 15% of growing bacteria produce dimeric chromosomes during DNA replication. These dimers are resolved by XerC and XerD, two tyrosine recombinases that target the 28-nucleotide motif (dif) associated with the chromosome's replication terminus.

Prophylactic Addition of Glucose Suppresses Cyanobacterial Abundance in Lake Water
Life, 2022 To mitigate harmful cyanobacterial blooms (HCBs), toxic algicides have been used, but alternative methods of HCB prevention are needed. Our goal was to test the prophylactic addition of glucose to inhibit HCB development, using Microcystis and the toxin ...
