Disease relevance of aroD


High impact information on aroD

  • DNA from these transformants can be recovered by retransformation back into E. coli aroD recipients and selection for chloramphenicol resistance [1].
  • The shikimate pathway enzyme 3-dehydroquinase is very susceptible to inactivation by the group-specific reagent diethyl pyrocarbonate (DEP) [6].
  • These genes code for 3-dehydroquinase enzymes of type II, involved in the catabolism of quinic acid [7].
  • All recombinant cosmids selected for their aroD complementation property carry this sequence [8].
  • No DNA sequence homology has, however, been detected by Southern hybridization between the cloned fragment and the aroD gene of E. coli or the qa2 (catabolic dehydroquinase) gene of Neurospora crassa [8].

Chemical compound and disease context of aroD


Biological context of aroD


Associations of aroD with chemical compounds

  • The presence of shikimic acid in the growth medium restores the ability of an aroD mutant to synthesize cmo5U, while O-succinylbenzoate, which is an early intermediate in the synthesis of menaquinone, does not [15].
  • The addition of an aroD deletion results in a requirement for an aromatic precursor of para-aminobenzoic acid (PABA), an essential bacterial metabolite not present in mammalian tissues [11].
  • The tetracycline-sensitive derivatives of Tn10 mutants obtained were selected on Bochner's medium and checked by DNA-DNA hybridization using aroA and aroD gene specific probes [2].
  • A stable mutation was introduced into the aroD gene of S. typhimurium C5 [4].
  • Additionally we have overproduced and purified the qutB-encoded quinate dehydrogenase and overproduced the qa-2 encoded type II 3-dehydroquinase of Neurospora crassa [16].
