    Phenotypes of a mutant

  • a ''[SW|ysbA]-[SW|ysbB]'' mutant is delayed in pellicle formation [Pubmed|26060272]
  • a ''[SW|ywbH]-[SW|ywbG] [SW|yxaK]-[SW|yxaC] [SW|ysbA]-[SW|ysbB]'' triple mutant is severely delayed in pellicle formation [Pubmed|26060272]

    • The protein

    Protein family

  • LrgB subfamily (according to Swiss-Prot)

    • [SW|Localization]

  • cell membrane (according to UniProt)

    • Expression and Regulation

    Operon

  • ''[protein|search|ysbA]-[protein|search|ysbB]'' [Pubmed|21815947]
  • ''[protein|search|ysbB]'' [Pubmed|8969504]

    • Regulation

  • induced by acetate [Pubmed|26060272]
  • induced by pyruvate [SW|LytT] [Pubmed|27422364]
  • subject to catabolite repression [SW|CcpA] [Pubmed|27422364]

    • Regulatory mechanism

  • [SW|LytT]: transcription activation [Pubmed|27422364]
