Regulation model of ompX mRNA under H₂O₂ stress. A Binding sites of the oxyS, micA and cyaR sRNAs in the 325 bp-regulatory region of ompX mRNA (the whole transcript is 836 bp long) under oxidative stress (oxyS in light blue, cyaR in orange, and micA in purple, translation start site in pink). B Schematic representation of the proposed interaction of oxyS sRNA with the ompX mRNA. The prediction was made using IntaRNA [4, 49],numbers indicate positions in the ompX mRNA and the oxyS sRNA sequence, respectively
