Additional information

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
    • repressed in the absence of good nitrogen sources (glutamine or ammonium) (TnrA) PubMed
    • repressed during growth in the presence of branched chain amino acids (CodY) PubMed
  • Regulatory mechanism: CodY: transcription repression PubMed, glucose regulation: CcpA PubMed, repression by BCAA: tRNA-controlled RNA switch (T-box) that mediates termination/antitermination
