    The protein

    Catalyzed reaction/ biological activity

  • required for the uptake of quorum sensing peptides such as [protein|search|PhrH] [Pubmed|21908671]
  • Protein family

  • ABC transmembrane type-1 domain (according to Swiss-Prot)
  • [SW|Localization]

  • cell membrane [Pubmed|10092453,18763711]
  • [SW|Interactions]

  • ([protein|search|OppD]-[protein|search|OppF])-([protein|search|OppB]-[protein|search|OppC])-[protein|search|OppA] [Pubmed|10092453]
  • Expression and Regulation

    Operon

  • ''[protein|search|oppA]-[protein|search|oppB]-[protein|search|oppC]-[protein|search|oppD]-[protein|search|oppF]'' [Pubmed|1901616]
  • Regulation

  • expressed in the absence of good nitrogen sources (glutamine or ammonium) ([protein|search|TnrA]) [Pubmed|12823818]
  • repressed during exponential growth ([protein|search|ScoC]) [Pubmed|10383984]
  • Regulatory mechanism

  • [protein|search|TnrA]: transcription activation [Pubmed|12823818]
  • [protein|search|ScoC]: transcription repression [Pubmed|10383984]
  • [protein|search|CodY]: transcription repression, no derepression occurs, however, in a ''[protein|search|codY]'' mutant, due to increased repression by [protein|search|ScoC] [Pubmed|25966844]
  • Biological materials

    Mutant
