(A) The rpoS gene encodes the σ S subunit of RNA polymerase needed for the cell stress response.Translation is inhibited by a stem–loop at the 3′ end of the rpoS mRNA leader that masks the Shine–Dalgarno (SD) ribosome binding sequence (Brown and Elliott 1997).Base pairing with complementary …
DsrA RNA is a non-coding RNA that regulates both transcription, by overcoming transcriptional silencing by the nucleoid-associated H-NS protein, and translation, by promoting efficient translation of the stress sigma factor, RpoS. These two activities of DsrA can be separated by mutation: … Visualizza altro There is experimental evidence to suggest that DsrA interacts with the protein-coding genes hns, rbsD, argR, ilvI and rpoS via an anti-sense mechanism.

An increasing number of RNAs have been recently shown to possess regulatory functions similar to those of proteins. In bacteria, these regulatory RNAs are usually noncoding and are short size (50–500 nts) transcripts that are often referred to as small RNAs (sRNAs) [1], [2]. diy black cat costume girl
