  Description: PubMed

  Sigma factors

  • SigA: sigma factor, PubMed (two promoters, about 140bp and 200bp upstream of the start codon), in SigA regulon

  Regulatory mechanism

  • stringent response: negative regulation, in stringent response

  Regulation

  • strongly repressed in response to glucose starvation in M9 medium PubMed
  • likely autorepression of operon expression upon binding of excess of one ribosomal protein to the untranslated region of the mRNA PubMed

  Additional information

  • term-seq has identified a potential novel regulatory RNA element (protein-dependent leader) including an intrinsic transcription terminator upstream of rpsJ PubMed
