In recent years, investigations on molecular interaction mechanisms between food proteins
and ligands have attracted much interest. The interaction mechanisms can supply much …

Bacillus thuringiensis (Bt) bacterium is found in various ecological habitats, and has natural
entomo-pesticidal properties, due to the production of crystalline and soluble proteins during …

Bacillus thuringiensis (Bt) is a Gram positive soil bacterium. This bacterium secretes various
proteins during different growth phases with an insecticidal potential against many …

The vegetative insecticidal proteins (Vips) secreted by Bacillus thuringiensis are regarded
as the new generation of insecticidal toxins because they have different insecticidal …

Two new modified Bacillus thuringiensis (Bt) proteins, Cry1Da_7 and Cry1B. 868, with
activity against fall armyworms (FAW), Spodoptera frugiperda (JE Smith), were evaluated for …

3D-Cry toxins, produced by the entomopathogenic bacterium Bacillus thuringiensis, have
been extensively mutated in order to elucidate their elegant and complex mechanism of …

Bacillus 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 …

Two new chimeric Bacillus thuringiensis (Bt) proteins, Cry1A. 2 and Cry1B. 2, were
constructed using specific domains, which provide insecticidal activity against key …

Cotton is a commercial crop of global importance. The major threat challenging the
productivity in cotton has been the lepidopteron insect pest Helicoverpa armigera or cotton …

Vip3 proteins are increasingly used in insect control in transgenic crops. To shed light on the
structure of these proteins, we used the approach of the trypsin fragmentation of mutants …
