Background

SgrS is an Hfq-binding small antisense RNA that is induced upon phosphosugar stress (Vanderpool, 2007). It forms a ribonucleoprotein complex with RNase E through Hfq to mediate silencing of the target ptsG mRNA encoding the major glucose transporter (Geissmann and Touati, 2004). A 31-nt-long stretch in the 3’ region of SgrS is partially complementary to the translation initiation region of ptsG mRNA, and a 6 nt region overlapping the Shine-Dalgarno sequence of the target mRNA turns out to be crucial for SgrS’ function, shown as Fig 2 (Kawamoto et al., 2006; Maki et al., 2010).
