Expression and regulation

• Operon: bglP-bglH-yxiE PubMed

• Sigma factor: SigA

• Regulation:
  • repressed by glucose (CcpA, LicT)
  • induced by salicin (LicT) PubMed

• Regulatory mechanism:
  • CcpA: transcription repression, (CcpA binding site overlaps -35 region)
  • LicT-dependent RNA switch (antitermination, lack of LicT-dependent antitermination in the presence of gucose due to the requirement of LicT to be phosphorylated by HPr
