Research Abstract

SgrS sRNA acts by baseparing with ptsG mRNA, resulting in translation inhibition and degradation of ptsG mRNA. We showed that the base pairing between SgrS and ptsG mRNA is directly responsible for translational silencing mediated by SgrS. We also identified a minimal base-pairing region of SgrS required for translational repression of ptsG mRNA. These results contribute to understanding the molecular mechanism by which Hfq-dependent sRNA act in bacteria.
