Disease relevance of Azoarcus


High impact information on Azoarcus


Chemical compound and disease context of Azoarcus

  • In this work, we have studied the transcriptional regulation of the bzd operon involved in the anaerobic catabolism of benzoate in the denitrifying Azoarcus sp. strain CIB [6].
  • We provide evidence for this hypothesis and show that benzoyl-CoA conversion in the bacterium Azoarcus evansii requires NADPH, O(2) and two protein components, BoxA and BoxB [10].
  • The conformation of a group I pre-tRNA(ile) from the bacterium Azoarcus was probed by ribonuclease T(1) and hydroxyl radical cleavage, and by native gel electrophoresis [11].
  • We collected nucleotide analog interference mapping (NAIM) data of the Azoarcus intron using 14 analogs that modified the phosphate backbone, the ribose sugar, or the purine base functional groups [12].
  • Changes in the size and shape of the Azoarcus group I ribozyme as a function of Mg(2+) and Na(+) concentration were followed by small angle neutron scattering [13].

Biological context of Azoarcus

  • One of the cloned 16S rRNA gene sequences comprised 70% of the culture and was phylogenetically 93% similar to both Azoarcus and Dechloromonas species, which have been shown to degrade aromatic compounds, including benzene, under nitrate-reducing conditions [14].
  • Two similar gene clusters coding for enzymes of a new type of aerobic 2-aminobenzoate (anthranilate) metabolism in the bacterium Azoarcus evansii [15].
  • The technique also predicted a similar binding site within the Azoarcus group I intron where the structure is not known [16].
  • The Azoarcus evansii gene which codes for phenylacetate-CoA ligase, an enzyme involved in the aerobic degradation of phenylacetate, was isolated from a genomic library, using as the probe a fragment of the gene which encodes the isoenzyme that is induced under anaerobic conditions [17].

Gene context of Azoarcus

  • The first step in anaerobic ethylbenzene mineralization in denitrifying Azoarcus sp. strain EB1 is the oxidation of ethylbenzene to (S)-(-)-1-phenylethanol [18].
  • Oligonucleotides deduced from N-terminal sequences of DP1 and DP4 specifically hybridized to chromosomal DNA of Azoarcus sp. strain BH72 in Southern hybridizations [19].
  • Surface-bound exo- and endoglucanases with some unusual regulatory features, detected in this study in a strain which is unable to metabolize cellulose or sugars, might assist Azoarcus sp. strain BH72 in infection of grass roots [20].
  • Role of a ferredoxin gene cotranscribed with the nifHDK operon in N(2) fixation and nitrogenase "switch-off" of Azoarcus sp. strain BH72 [21].
  • Comparative sequence analyses of the 16S rRNA of one isolate (T3 and M3) of each group revealed a close phylogenetic relationship for both groups of isolates to organisms of the genus Azoarcus [22].
