It is shown here that the bacterial insertion sequence IS911 exhibits a temperature‐sensitive
transposition phenotype. Previous results have demonstrated that elevated levels of the …

We have mutagenized a clinical strain of Salmonella enterica sv. typhi with mini-transposon
Tn 10 dTet (T-POP) to obtain conditional lethal (tetracycline-dependent) mutants with T-POP …

The inverted repeats (IRs) of the insertion element IS903 are composed of two functional
regions. An inner region, consisting of basepairs 6–18, is the transposase binding site. The …

In an attempt to increase our understanding of the mechanisms of conjugal transposition
among gram-positive bacteria, we analyzed the genetic and structural properties of a 1.2-kb …

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 …

Transcription and mobilization facilities of a group II intron, B. me. I1, which was classified
within a group IIB subclass and nested in a broad-spectrum mercury resistance transposon …

Tn5 transposase (Tnp) overproduction is lethal to Escherichia coli. Tnp overproduction
causes cell filamentation, abnormal chromosome segregation, and an increase in …

Tn4371is a 55-kb catabolic transposon originally isolated fromRalstonia eutrophaA5 that
encodes enzymes catalyzing the complete degradation of biphenyl. Unlike previously …

Transposons are found in a wide variety of forms throughout the prokaryotic world where
they actively contribute to the adaptive strategies of bacterial communities and hence, to the …

The role of integration host factor (IHF) in the regulation of the sigma 54-dependent promoter
Pu of the TOL plasmid of Pseudomonas putida has been examined. We have selected in …
