Amino acid sequence and entomocidal activity of the P2 crystal protein. An insect toxin from Bacillus thuringiensis var. kurstaki.

Abstract

The gene encoding the 66-kDa entomocidal protein (P2 protein or mosquito factor) from Bacillus thuringiensis var. kurstaki has been isolated by the use of a 62-mer oligonucleotide probe that encoded 21 amino acids of the P2 protein NH2 terminus. The DNA sequence of the gene, designated cryBI, was unique from the published sequences of other B. thuringiensis… (More)
