Abstract

The widespread use of Bacillus thuringiensis Cry proteins in pest control has led to resistance in some lepidopteran pests. Vip3 proteins, lacking sequence homology with Cry toxins, offer a promising alternative due to distinct insecticidal mechanisms. This study investigates how modulating interactions between domain III and the N-terminal region (P14–G22) of Vip3 proteins influences their activation efficiency and insecticidal activity.

Vip3Aa和Vip3Ca结构域III的结构和功能作用：对膜穿孔和杀虫效果的影响

苏云金芽孢杆菌Cry蛋白在害虫防治中的广泛应用已导致部分鳞翅目害虫产生抗药性。由于不同的杀虫机制，缺乏与Cry毒素序列同源性的Vip3蛋白提供了一个有希望的替代方案。本研究探讨了Vip3蛋白结构域III和n端区域（P14-G22）之间的相互作用如何影响其激活效率和杀虫活性。
