Regulatory small RNAs and rpoS may interact with Rex, as rex genes are able to inhibit T4 (rII+) plating if rpoS is deleted. (A) Rex activity is the ability of pHA1-delivered rex genes to reduce plating in the presence or absence of RII. Activity is derived by taking the inverse of the relative EOP of the sample in rex+ conditions (plasmid) compared to rex- conditions (no plasmid). Maximal Rex activity is the complete attenuation of T4rII (rII-) plating in presence of the rex pHA1 in E. coli BW25113 (wt). Absence of Rex activity is full plating of T4 (rII+) in presence of the rex+ pHA1 in E. coli BW25113 (wt). (B) rpoE and rpoS are regulated by ClpXP activity and respective regulatory small RNAs.
