    Phenotypes of a mutant

  • reduced acetoin production [pubmed|31113899]
  • impaired biofilm development [pubmed|31113899]

    • The protein

    Catalyzed reaction/ biological activity

  • binds the promoter region of the [gene|AAA45830B9C5428CADFA5551D33B513E9B1B7C8E|alsS]-[gene|355E70F55A28C6C2C24E8E326EFB673AC303FBEE|alsD] operon in the presence of acetate, activates transcription [pubmed|30039521]

    • Protein family

  • [SW|LysR family] (according to UniProt)

    • Effectors of protein activity

  • acetate (2 molecules per molecule of AlsR) acts as co-factor that triggers activity [pubmed|30039521]

    • Structure

  • [PDB|2H98] (from Acinetobacter baylyi, 34% identity)
