description
[Pubmed|9371452]
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]
expression is reduced in motile cells as compared to non-motile cells [pubmed|33782055]
regulatory mechanism
stringent response: negative regulation, in [regulon|other_regulator:stringent response|stringent response]
sigma factors
[protein|360F48D576DE950DF79C1A2677B7A35A8D8CC30C|sigA]: sigma factor, [Pubmed|9371452] (two promoters, about 140bp and 200bp upstream of the start codon), in [regulon|protein:360F48D576DE950DF79C1A2677B7A35A8D8CC30C|sigA regulon]
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]
