Webb1 aug. 1998 · Translation of rpoS mRNA is controlled by a cascade of interacting factors, including Hfq, H-NS, dsrA RNA, LeuO, and oxyS RNA that seem to modulate the stability of a region of secondary structure in the ribosome-binding region of the gene's mRNA. WebbFinally, oxidative stress is known to induce the RpoS regulon [22–23]. RpoS is the stationary phase sigma factor, which is induced in exponential phase in response to stress [24–26]. Genes expressed following RpoS regulon induction, namely catalases (KatE, KatG) and iron chelators (Dps), protect cells from ROS
