Abstact

Epsilon-toxin from Clostridium perfringens is a lethal toxin. Recent studies suggest that the toxin acts via an unusually potent pore-forming mechanism. Here we report the crystal structure of epsilon-toxin, which reveals structural similarity to aerolysin from Aeromonas hydrophila. Pore-forming toxins can change conformation between soluble and transmembrane states. By comparing the two toxins, we have identified regions important for this transformation.
