Nucleotide sequence of IS26, a new prokaryotic mobile genetic element.

The DNA sequence of a new IS element, the IS26, is 820 bp long and carries 14 bp perfect terminal inverted repeats. Upon integration, IS26 generates an 8 bp duplication of its target sequence. A large open reading frame within IS26 could code for a protein of 234 amino acids. On its reverse strand, IS26 also carries one large open reading frame, 591 bp long, which contains no stop codon within IS26.
