Four further single mutants ofN546(N546G,N546D,N546K,N546Δ), three double mutants and a triple mutant were constructed,and toxins were purified by isoelectric precipitation and an AKTA purifier 100 system.When bioassayed against H.armigera using purified toxins,N546ALC_(501.67μg/mLshowed 1.78 times increased toxicity than wide-type Cry1AcLC_(50 2.98μg/mL,and mutant N546D,N546K and N546Δshowed a great loss in toxicity.

对N546进一步突变，获得了突变子N546G、N546D、N546K和删除突变N546Δ及3个双突变和1个三突变，利用等电点沉淀法和AKTApurifier 100系统纯化了毒素蛋白，生测发现N546ALC_(50为1.67μg/mL对棉铃虫毒力比野生型Cry1AcLC_(50为2.98μg/mL提高了1.78倍，而N546D、N546K和N546Δ的毒力则降低了80～90%。
