Description
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
expression is reduced in motile cells as compared to non-motile cells PubMed
Regulatory mechanism
stringent response: negative regulation, in stringent response
Sigma factors
SigA: sigma factor, PubMed (two promoters, about 140bp and 200bp upstream of the start codon), in 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
