Abstract

The Vip3 family proteins from Bacillus thuringiensis are thought to exert their insecticidal activity through pore formation. Here authors present cryo-EM structures of a Vip3 family toxin in both inactive and activated forms and show the activated Vip3Bc1 in its pore forming conformation on the membrane.
