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
- Regulatory mechanism: glucose regulation: CcpA PubMed, repression by BCAA: tRNA-controlled RNA switch (T-box) that mediates termination/antitermination, transcription repression by CodY
