Expression and regulation
- Regulation: repressed by glucose (CcpA) , carbon catabolite repression, induction by fructose
- Regulatory mechanism: CcpA: transcription repression, catabolite repression: transcription repression by CcpA, transcription activator LevR is less active in the presence of glucose; induction: transcription activation by LevR
