A cry‐related sequence, designated cryX (EMBL X75019), was localized upstream of cry IG, the δ‐endotoxin gene cloned from spp. galleriae of Bacillus thuringiensis and sequenced earlier [(1991) FEBS Lett. 293, 25‐28]. Analysis of the cryX complete nucleotide sequence enabled us to explain its virtual crypticity and to reveal the chimeric structure of the genes, cryX and cry IG. The amino acid sequence of 1,151 residues encoded by the continuous reading frame of cryX is similar to the other δ‐endotoxins but differs essentially from them.
