• We found three particular groups-bacteroidetes, proteobacteria, and firmicutes-but we found that there was a higher abundance of proteobacteria in [colorectal cancer] cases than in controls," lead author Temitope O. Keku, PhD, of the Center for Gastrointestinal Biology and Disease at the University of North Carolina at Chapel Hill, said in a telephone interview. (lww.com)
  • All communities were highly diverse and dominated by the phyla Firmicutes, Bacteroidetes, Tenericutes, Actinobacteria and Proteobacteria. (wiley.com)
  • On the basis of the phylogenetic analyses, chemotaxonomic and biochemical characteristics, we propose that strain CCUG 44693T (CIP 108310T) represents a new genus of the α-1 subclass of the Proteobacteria for which we propose the name Rhodovarius lipocyclicus gen. nov. sp. (csic.es)
  • Isolation of a new species of nitrogen-fixing Proteobacteria, from the rice rhizosphere, belonging to the genus Burkholderia. (ugent.be)
  • Tchogha Zanbil is download Bergey\'s Manual of Systematic Bacteriology 2nd Ed Vol 2 Proteobacteria to the new people of the molecular weather of Dur Untash, the discrete key of the clear Kingdom. (elvisofboston.com)
  • Bioinformatic analyses revealed that MCE domains are widely distributed across bacterial phyla but multi MCE domain-containing proteins evolved in Proteobacteria from single-domain proteins. (nature.com)
  • Complementing our previous findings that all three proteins bind phospholipids, results presented here indicate that multi-domain proteins evolved in Proteobacteria for specific functions in maintaining cell envelope homeostasis. (nature.com)
  • Given the wide distribution of MCE domains across Proteobacteria, we sought to understand functional and evolutionary relationships between these proteins, with a particular focus on those found in E. coli . (nature.com)
  • Phylogenetic analyses using the 16S rRNA gene sequence of the isolate indicated that it represents a new lineage in the α-1 subclass of the Proteobacteria, with the highest sequence similarity of 93.3% to the type strain of Muricoccus roseus. (csic.es)
  • The isolate also contained 18:1 2-OH and other fatty acids typical for members of the α-1 subclass of the Proteobacteria in addition to 10:0 2-OH in low amounts, not detected in members of closely related genera. (csic.es)
  • Comparative 16S rDNA sequence analysis demonstrated that these endosymbionts form a novel, monophyletic lineage within the beta-Proteobacteria, showing less than 90% sequence similarity to all other recognized members of this subclass. (microbiologyresearch.org)
  • Four isolates were identical with respect to small-subunit rRNA sequence over 891 positions compared and fall within a unique clade in the c-subclass of the Proteobacteria. (mblwhoilibrary.org)
  • Membrane fatty acids as phenotypic markers in the polyphasic taxonomy of methylotrophs within the Proteobacteria. (nih.gov)
  • The PLFA phenotype relationships compare favourably with phylogenetic associations based on 16S rRNA data for methylotrophs and will continue to be a valuable phenotypic marker for Proteobacteria taxonomy. (nih.gov)
  • We identified novel transcriptional regulators that control the hexuronate and aldarate utilization genes in four families of proteobacteria. (asm.org)
  • We used comparative genomics to reconstruct d -galacturonic and d -glucuronic acid catabolic pathways and associated transcriptional regulons involving the tripartite ATP-independent periplasmic (TRAP) family transporters that bind hexuronates in proteobacteria. (asm.org)
  • The reconstructed catabolic pathways are interconnected with each other metabolically and coregulated via the GguR regulons in proteobacteria. (asm.org)
  • All "Proteobacteria" are gram-negative (though some may stain Gram-positive or Gram-variable in practice), with an outer membrane mainly composed of lipopolysaccharides. (wikipedia.org)
  • This review describes what is currently known about the phylogenetic and physiological diversity of the iron-oxidizing proteobacteria, their significance in the environment (on the global and micro scales), and their increasing importance in biotechnology. (microbiologyresearch.org)
  • Most importantly, we show that the DUF2336 domain of SpmY is functionally conserved among the α-proteobacteria, revealing a possibly conserved mechanism to regulate TacA. (pnas.org)
  • Although several studies have pointed towards the importance of the sigma factor, σ 54 , in regulating virulence, biofilm formation, and cell cycle control in α-proteobacteria, knowledge on its activators and their regulation is incomplete. (pnas.org)
