  • regulatory mechanism

  • [regulon|stringent response|stringent response]: negative regulation, in [regulon|stringent response|stringent response]
  • regulation

  • strongly repressed in response to glucose starvation in M9 medium [Pubmed|23033921]
  • likely autorepression of operon expression upon binding of excess of one ribosomal protein to the untranslated region of the mRNA [Pubmed|17616982]
  • additional information

  • term-seq has identified a potential novel regulatory RNA element (protein-dependent leader) including an intrinsic transcription terminator upstream of ''rpsJ'' [Pubmed|27120414]
