A 5.7-kb EcoRI fragment was cloned from plasmid DNA of Bacillus thuringiensis strain M15. It contains two insertion sequences (IS), IS231M2 and -M1 in the 5'-3' order, arranged in tandem, in same orientation, separated by a 540-bp region. The primary structure is typical of a composite transposon, here of 3847 bp in length, for which the name Tn231M is proposed. Each IS is delimited by 18-bp inverted repeats (IR), and flanked by 11-bp direct repeats (DR). Both IS share 99.3% nucleotide identities. IS231M1 has a single open reading frame (ORF) which encodes a putative 477-amino-acid transposase. IS231M2 has two smaller ORFs: ORF1 and ORF2, which could code for polypeptides of 329 and 118 amino acids in length, respectively. Further analysis reveals that the regions upstream of IS231M2, and downstream of -M1, and the 540-bp region, contain additional pairs of IR and DR. Interestingly, potential annealing between all pairs of IR and DR could generate two unusual cloverleaf secondary structures.
