Vip3C proteins from Paenibacillus spp. for controlling lepidopteran crop pests [PDF]
Applied and Environmental MicrobiologyNew proteins are needed to control insects not controlled with Bacillus thuringiensis (Bt) crops, and those evolving resistance to Bt crops. These proteins are increasingly being reported from non-Bt organisms to control Bt-resistant insects.

N-Terminal α-Helices in Domain I of Bacillus thuringiensis Vip3Aa Play Crucial Roles in Disruption of Liposomal Membrane [PDF]
ToxinsBacillus thuringiensis Vip3 toxins form a tetrameric structure crucial for their insecticidal activity. Each Vip3Aa monomer comprises five domains. Interaction of the first four α-helices in domain I with the target cellular membrane was proposed to be a
