Expression and regulation

  • Regulation:
    • repressed by casamino acids PubMed
    • expressed in the absence of branched-chain amino acids (BCAA)
    • expression is stimulated in the presence of glucose PubMed
    • repressed by CodY PubMed
    • less expressed under conditions of extreme iron limitation (FsrA) PubMed
  • Regulatory mechanism:
    • CodY: transcription repression PubMed
    • glucose regulation: CcpA PubMed
    • repression by BCAA: tRNA-controlled RNA switch (T-box) that mediates termination/antitermination
