Expression and Regulation

Operons

• Genes: infC-rpmI-rplT-ysdA
  Description: PubMed

  Regulatory mechanism

  • stringent response: negative regulation, in stringent response
  • RplT: termination, via binding to a RNA switch in the infC leader region causes transcription termination, in RplT regulon

  Regulation

  • RelA dependent downregulation (Class I) during stringent response PubMed

  Additional information

  • autorepression of infC-rpmI-rplT-ysdA expression upon binding of excess RplT to the untranslated region of the mRNA PubMed
  • expression of IF3 is uncoupled from that of L35 and L20 by RNase Y-dependent mRNA processing PubMed
