摘要
The Cry2Aa3 gene was introduced into asporogenic Bacillus thuringiensis, and the synthesized protoxin killed Bombyx mori and Lymantria dispar larvae. Chymotrypsin hydrolyzed the linkages between 49Tyr/Va150 and 145Lys/Ser146 in the protoxin, and 50- and 58-kDa fragments were generated, respectively. Both peptides killed the larvae of both insects.
