Cloned diphtheria toxin within the periplasm of Escherichia coli causes lethal membrane damage at low pH.
Acidic pH within endosomal vesicles of sensitive animal cells triggers a conformational change in diphtheria toxin (DT) that is believed to cause the B chain to insert into the vesicular membrane and the enzymic A chain to be released into the cytosol. In artificial lipid bilayers, DT forms ion-cond...
