Abstract

The isolation of two multi-resistance transposons, Tn and Tn, and their relation to Tn and Tn, is described. A 1·7 kb segment present in Tn and Tn was identified as an IS element by -independent transposition, resulting in a Cointegrate structure that carries two direct repeated copies of the IS element. By the isolation of this IS element we demonstrated that transposition is one mechanism leading to sequence variations in Tn-like structures, especially in the region between the operon and the gene.
