Expression and regulation

• Operon: epsA-epsB-epsC-epsD-epsE-epsF-epsG-epsH-epsI-epsJ-epsK-epsL-epsM-epsN-epsO PubMed

• Expression browser: epsJ PubMed

• Sigma factor: SigA PubMed

• Regulation:
  • repressed by SinR PubMed

• Regulatory mechanism:
  • SinR: transcription repression PubMed
  • AbrB: transcription repression PubMed

• Additional information:
  • induction by sequestration of SinR by SinI or SlrA PubMed
  • the epsA-epsB-epsC-epsD-epsE-epsF-epsG-epsH-epsI-epsJ-epsK-epsL-epsM-epsN-epsO operon is not expressed in a ymdB mutant PubMed
  • the amount of the mRNA is substantially decreased upon depletion of RNase Y (this is likely due to the increased stability of the sinR mRNA) PubMed
  • the EAR riboswitch (eps-associated RNA switch) located between epsB and epsC mediates processive antitermination and allows expression of the long eps operon PubMed
