C. botulinum E Toxin

Clostridium botulinum is a gram-negative bacterium that produces seven related toxins, called botulinum toxin types A, B, C1, D, E, F, and G. The toxin is synthesized as a protoxin of 150kDa, which is susequently cleaved to a light (L) and heavy (H) chain that remain linked by a disulfide bond. Only botulinum toxin types A, B, E, F and H cause disease in humans. Types A, B, and E are associated with food-borne illness, with type E specifically associated with fish products.
