We have examined the targeting preference of the bacterial insertion element IS 903 by
determining the sites of insertion of a large number of transposition events into the 55-kb …

The transposon Tn7 is unusual as it transposes at high frequencies from episomal elements
to a unique site in the Escherichia coli chromosome. This unique site is within a region of …

We describe in Streptococcus agalactiae an atypical family of conjugative transposons
named TnGBSs which associates DDE transposition and conjugation. We present evidence …

The bacterial insertion sequence IS903 has the unusual ability to transpose both
replicatively and non‐replicatively. The majority of products are simple insertions, while co …

An unusual subset of DNA-binding proteins, termed cis-acting proteins, has been shown to
act preferentially at their site of synthesis; the transposases of several bacterial insertion …

The transposable element IS 801, isolated from plasmid pMMC7105 of Pseudomonas
syringae pv. phaseolicola, transposes in Escherichia coli to plasmid targets, expressing a …

The Vibrio cholerae SXT element is a conjugative self-transmissible chromosomally
integrating element that encodes resistance to multiple antibiotics. SXT integrates in a site …

The conjugative transposon Tn916 (15 kilobases), originally identified in Streptococcus
faecalis DS16, has been cloned as an intact element on the pBR322-derived vector pGL101 …

The transposase of the bacterial insertion sequence IS1 is normally expressed by inefficient
translational frameshifting between an upstream reading frame which itself specifies a …

Transposon Tn7 inserts at high frequency into a specific site in the Escherichia coli
chromosome called attTn7. We show that the point of Tn7 insertion in attTn7 lies within the …
