Disease relevance of Azospirillum

 

High impact information on Azospirillum

  • Nevertheless, the indole-3-pyruvate decarboxylase encoding ipdC gene is crucial in the overall IAA biosynthesis in Azospirillum [6].
  • In Azospirillum brasilense and H. seropedicae (alpha- and beta-subgroup, respectively), NifA is inactive in conditions of excess nitrogen [6].
  • Azospirillum brasiliense converts L-arabinose to alpha-ketoglutarate via five hypothetical enzymatic steps [7].
  • Azospirillum brasilense glutamate synthase (GltS) is the prototype of bacterial NADPH-dependent enzymes, a class of complex iron-sulfur flavoproteins essential in ammonia assimilation processes [8].
  • Glutamate synthase genes of the diazotroph Azospirillum brasilense. Cloning, sequencing, and analysis of functional domains [9].
 

Chemical compound and disease context of Azospirillum

  • The 35.8 kDa C-terminal module of Pel10A was shown to have 30 and 36% identities with the family 10 pectate lyases from Azospirillum irakense and an alkaliphilic strain of Bacillus sp. strain KSM-P15, respectively [10].
  • Here we report on the presence of sulfated lipopolysaccharide molecules in Azospirillum brasilense, a plant growth-promoting rhizosphere bacterium [11].
  • Auxins upregulate expression of the indole-3-pyruvate decarboxylase gene in Azospirillum brasilense [12].
  • Uptake hydrogenase activity in denitrifying Azospirillum brasilense grown anaerobically with nitrous oxide or nitrate [13].
  • Fructose uptake and catabolism in Azospirillum brasilense is dependent on three fructose-inducible enzymes (fru-enzymes): (i) enzyme I and (ii) enzyme II of the phosphoenolpyruvate:fructose phosphotransferase system and (iii) 1-phosphofructokinase [14].
