Type II toxin – antitoxin modules encode a stable toxin that inhibits translation, replication or cell wall synthesis and an unstable protein antitoxin that neutralizes the toxin by direct protein – p
lacI-Phsp or lacI-Phspζ cells bearing plasmid pCB799 (xylR-PXylAε) were grown in MMS7 containing 0.005% Xyl to allow limiting expression of ε2 antitoxin, ε(+), to titrate basal expression of the wt ζ
One mechanism by which bacteria survive environmental stress is through the formation of bacterial persisters, a sub-population of genetically identical quiescent cells that exhibit multidrug toleranc
