The ratio between the two forms of DsrA (F/T) sRNA varies in a temperature-dependent manner, with relatively more T formed at higher temperatures. At low temperature, the F form of DsrA outnumbers the T form.
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. Web4 feb 2024 · DsrA sRNA was shown to be involved in the suppression of Rho-dependent transcription termination of rpoS ; in this case it was used as a negative control (Fig. 6B, …
WebAs expected, base pairing between rpoS mRNA and DsrA sRNA protected the DsrA binding site in the inhibitory stem from modification, reducing the SHAPE reactivity by ∼30–40% (Fig. 1B). The SHAPE reactivity of the upstream and down-stream domains did not change appreciably, however, suggesting
