Nucleotide sequence of the Pseudomonas aeruginosa insertion sequence IS222: another member of the IS3 family.
Sequence analysis of the Pseudomonas aeruginosa insertion sequence element IS222 revealed it to be 1234 bp in size with 23 bp imperfect terminal inverted repeats. Insertion caused a 5-bp duplication of the insertion site. Two ORFs were identified, one of which, ORFA, could encode a basic (pI 10.5) polypeptide with a mass of 11,709. This sequence bears strong homology to the putative ORFA product from the Shigella dysenteriae insertion sequence element IS911, which is a member of the IS3 family of insertion elements. As with other members of this group the nucleotide sequence contains a "frameshift window" (AAAAAAG; M. Chandler and O. Fayet (1993). Mol. Microbiol. 7, 497-503) at which ribosome slippage can result in a fusion protein (ORFAB).
