Additional information
Expression and regulation
- 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
