Disease relevance of Proteobacteria


High impact information on Proteobacteria

  • Nodulation of legumes by members of the beta-subclass of Proteobacteria [6].
  • Unlike other eukaryotes, dinoflagellates containing peridinin use a form of RuBisCO (form II) previously found only in some species of proteobacteria [7].
  • In bacteria in the phylum Proteobacteria that contain HPr kinase and XPr, the latter may be at the center of a complex regulatory network involving both CCR and the Ntr system [8].
  • The results extend the structural analogies between the secondary quinone binding site in D1 and in subunit L of the photosynthetic reaction center in purple bacteria [9].
  • Acyl-homoserine lactone (acyl-HSL) signaling is thought to mediate quorum sensing in many species of Proteobacteria [10].

Chemical compound and disease context of Proteobacteria

  • Femtosecond dynamics of the forbidden carotenoid S1 state in light-harvesting complexes of purple bacteria observed after two-photon excitation [11].
  • The Calvin-Benson-Bassham cycle constitutes the principal route of CO2 assimilation in aerobic chemoautotrophic and in anaerobic phototrophic purple bacteria [12].
  • The proteins encoded by hscA and hscB, the chaperone HSP66 and the co-chaperone HSP20, have been shown to be required for the synthesis of 2Fe-2S clusters on ferredoxin in proteobacteria [13].
  • The two best characterised obligately aerobic NTA-utilising genera (Chelatobacter and Chelatococcus) are members of the alpha-subgroup of Proteobacteria [14].
  • The periplasmic nitrate reductase (Nap) is wide-spread in proteobacteria [15].

Biological context of Proteobacteria


Anatomical context of Proteobacteria


Gene context of Proteobacteria


Analytical, diagnostic and therapeutic context of Proteobacteria

  • Sequence analysis confirmed the genetic data and showed the presence of crtD and crtC genes downstream of the puf operon, a localization different from that known for other purple bacteria [18].
  • Hydrogen ion equilibria of the reaction center protein from photosynthetic purple bacteria Rhodobacter sphaeroides and Rhodobacter capsulatus dissolved in micellular solution were studied by acid-base titration to estimate the water accessibility of protonatable residues of the protein determined from structural data [28].
  • In situ hybridization results have indicated that Nitrosomonas-like ammonia oxidizing and Nitrospira-related nitrite oxidizing bacteria were intensively present in vigorous flocs in nitrification biofilter while carbonaceous bacteria belong to beta subclass of Proteobacteria were considerably dominant in oxidation ditch [29].
