Expression and regulation

• Operon: bglP-bglH-yxiE PubMed

• Sigma factor: SigA

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

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