Transposition activity in bacteria is generally maintained at a low level. The activity of mobile
DNA elements can be controlled by bacterially encoded global regulators. Regulation of …

Transpositional activity of mobile elements is not constant. Conditional regulation of host
factors involved in transposition may severely change the activity of mobile elements. We …

We have previously shown that both ends of the Tn 3 family transposon Tn 4652 contain
integration host factor (IHF) binding sites and that IHF positively regulates expression of the …

Tn 4652 is a derivative of the toluene degradation transposon Tn 4651 that belongs to the
Tn 3 family of transposons (M. Tsuda and T. Iino, Mol. Gen. Genet. 210: 270–276, 1987). We …

The Fis (factor for inversion stimulation) protein of Escherichia coli was found to influence
the frequency of transposon Tn5 and insertion sequence IS50 transposition. Fis stimulated …

Transpositional activity of mobile elements can be induced by different environmental
stresses. Here, we present evidence that transposition of Tn 4652 is elevated in stationary …

Pseudomonas stutzeri AN10 has two IS L3-like insertion sequences (ISs). One of them has
been recently described as IS Pst9. In this study we show that the second IS, situated 4.5 kb …

Transposition is a DNA reorganization reaction potentially deleterious for the host. The
frequency of transposition is limited by the amount of transposase. Therefore, strict …

We show in this work that disruption of the hfq gene in Escherichia coli causes a large
increase in IS10 transposition when IS10 is present on a multi‐copy plasmid. Hfq is an RNA …

The bacterial insertion sequence (IS) IS26 mobilizes and disseminates antibiotic resistance
genes. It differs from bacterial IS that have been studied to date as it exclusively forms …
