Expression and regulation

• Operon: cysH-cysP-sat-cysC-ylnD-ylnE-ylnF

• Sigma factor: SigA

• Regulation:
  • repressed by casamino acids PubMed
  • repressed in the presence of cysteine (CymR)
  • induced by methionine starvation (S-box) PubMed

• Regulatory mechanism:
  • S-box: transcription termination/ antitermination, the S-box riboswitch binds S-adenosylmethionine resulting in termination PubMed
  • CymR: transcription repression
