Abstract
A gene cryIg coding for entomocidal protein δ‐endotoxin of Bacillus thuringiensis ssp. galleriae str. 11‐67 named CryIG has been cloned and sequenced (EMBL accession number X58120). The deduced amino acid sequence that contains 1156 amino acid residues shows only 28% of identical residues, when compared with other δ‐endotoxins of the CryI family. The extent of identity is substantially higher for some regions of the sequence (‘conserved blocks’), that presumably bear important structural or functional properties. This implies that CryIG δ‐endotoxin follows the same type of polypeptide chain folding as other Cryl proteins, whereas peculiarities of primary structure help to explain its unique specificity.Keywords
