title: Cloning and nucleotide sequence of different iso-IS231 elements and their structural association with the Tn4430 transposon in Bacillus thuringiensis.
abstract: A family of five repetitive sequences (RS) has been isolated from a plasmid DNA library of Bacillus thuringiensis strain berliner 1715. In a previous paper [Mahillon et al., EMBO J. 4(1985)3895-3899] one of these was shown to harbor all the features of an IS element (IS231). Further nucleotide sequence analysis revealed that two other RS, flanking the delta-endotoxin gene, are actually variants of IS231. Comparison of the nucleotide sequences surrounding the iso-IS231 elements showed a unique structural association between some of these elements and the transposon Tn4430. Although these IS231 elements have transposed into Tn4430, both these IS231 s and the transposon Tn4430 remain structurally intact.
