title: IS150: distribution, nucleotide sequence and phylogenetic relationships of a new E. coli insertion element.
abstract: Recently we identified the new insertion (IS) sequence IS150 in various strains of Escherichia coli K-12. We have screened other strains of E. coli and Salmonella typhimurium for the presence of homologous sequences. The strains of E. coli K-12 and W tested contain one or more copies of homology to IS150. We have also determined the complete nucleotide sequence of a copy of IS150 inserted into IS1. Comparison of nucleotide and deduced amino acid sequences of IS150, IS2, IS3, IS51, IS600 and IS629 reveals significant homologies suggesting that these elements are members of a family of phylogenetically related insertion sequences.
