Disease relevance of arcA

  • The mapping and the dye sensitivity suggest that these mutants are defective in the arcA and arcB genes, not previously identified in Salmonella typhimurium [1].
 

High impact information on arcA

  • A deletion in the rpoS gene, on the other hand, resulted in non-restricted, increased arcA expression in stationary-phase cultures under microaerobic conditions [2].
  • In the wild-type strain, rpoS transcription was greater under aerobic than under microaerobic conditions, whereas transcription of arcA was suppressed by aerobiosis [2].
