Omps may play a role in Rex, as their deletions affect Rex activity. In particular, ΔompF, ΔompL, ΔompT, ΔompW, and ΔompX attenuate Rex activity. (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) Omps mediate ion transport as regulated by rpoE and rpoS.
