Genes
Description
Regulation
autorepression of rpsD expression upon binding of excess RpsD to a RNA switch in the untranslated region of the rpsD 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
Additional information
term-seq has identified a potential novel regulatory RNA element including an intrinsic transcription terminator upstream of rpsD PubMed
