Web13 nov 2013 · The sRNA DsrA, which is mainly transcribed at low-growth temperature 16, 17 (≤ 25 °C), is necessary for translational activation of rpoS mRNA 18 under these conditions. The DsrA-rpoS mRNA interaction counteracts an iss that impedes ribosomal access to the rbs of rpoS. 19 In vivo DsrA ... Web27 apr 2024 · In this study, we show that the simultaneous overexpression of the noncoding small RNA (sRNA) DsrA and the sRNA chaperone Hfq, which act as RpoS activators, significantly increased acid tolerance in terms of cell growth under modest acidic pH, as well as cell survival upon extreme acid shock.

Web1 ago 2024 · DsrA is reasonably abundant in cells grown under many conditions. Deletion of this sRNA reduces the basal level of RpoS in exponential phase and abolishes the increase in RpoS normally seen at low temperature ( 34 ). Other physiologically important regulators of dsrA transcription may well exist.
