Membrane translocation and channel-forming activities of diphtheria toxin are blocked by replacing isoleucine 364 with lysine.
A mutant of diphtheria toxin in which Ile-364 was replaced by Lys was at least 500-fold less toxic to Vero cells than the parental toxin. Its ability to undergo low-pH-triggered translocation across the plasma membrane was greatly diminished, as was its ability to form ion-conductive channels. In ad...
