Anthrax is an acute infectious disease caused by B. anthracis, a gram-positive and spore-forming bacterium. Anthrax toxin is a tripartite AB toxin composed of a receptor binding/pore-forming moiety, protective antigen (PA), and two catalytic moieties, edema factor (EF) and lethal factor (LF). Anthrax toxin PA binds to cell-surface receptors, where it gets activated by furin, and assembles into a ring-like heptameric structure. The toxin-receptor complex is internalized into endosomes where the acidic pH triggers PA pore formation on the endosomal membrane that translocates the toxin catalytic moieties. Recent study has shown that anthrax toxin receptors play a critical role in …
