 In contrast, LeuO inhibits "rpoS" translation by repressing "dsrA" expression and the histone-like protein HN-S (and its paralog StpA) inhibits "rpoS" translation via an unknown mechanism.In addition, H-NS, LeuO, Hfq and DsrA form an interconnected regulatory network that ultimately controls "rpoS" translation.RpoS translation was also shown to be controlled in other bacterial species, beside Escherichia coli.
