Effects of the 20-kilodalton helper protein on Cry1Ac production and spore formation in Bacillus thuringiensis
Article Abstract:
A 20-kDa helper protein in Bacillus thuringiensis enhances the production of Cry1Ac toxin. The P20 protein increases toxin yield more than two-fold, produces larger crystals, and Cry1Ac is more toxic against Heliothis armigera larvae when synthesized in the presence of the helper protein.

Bacillus thuringiensis delta-endotoxin Cry1 hybrid proteins with increased activity against the Colorado potato beetle
Article Abstract:
Researchers have constructed a hybrid of the Bacillus thuringiensis Cry1Ba and Cry1Ia proteins that is toxic to coleoptera such as the Colorado potato beetle. Normally, the Cry1 proteins are only toxic to lepidoptera.
