<p>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).</p>

ptsG2-GFP (ptsG2 5'UTR fused with gfp)

ptsG2 is the C87G mutant of ptsG(wt) and the conjugate part of SgrS2 in our comparator device (see Fig. 1).

680px PtsG is a glucose permease which is subordinate to phosphotransferase system and serves as a transporter. Here,we studied this mRNA perform the conjugate part of the small RNA regulator sgrS(wt)[1]. ptsG mRNA is regulated by SgrS by short, imperfect base-pairing interactions, and its expression is thus repressed.
