Insertion sequences (ISs) constitute an important component of most bacterial genomes.
Over 500 individual ISs have been described in the literature to date, and many more are …

The expression of an increasing number of genes of both prokaryotic and eukaryotic origin
has been shown to be regulated at the translational level by programmed (sequence …

This chapter is an update of a survey of insertion sequences (ISs) published in 1998.
Researchers have retained the same basic structure: a first section including some key …

Living organisms are defined by the genes they possess. Control of expression of this gene
set, both temporally and in response to the environment, determines whether an organism …

We present evidence that excision of the nonreplicative transposon Tn10 involves three
distinct chemical steps, first-strand nicking, hairpin formation, and hairpin resolution. This …

The eight IS 231 variants characterized so far (IS 231 A‐F, V and W) display similar
transposases with an overall 40% identity. Comparison with all the proka‐ryotic …

IS1294, found on the ColD-like resistance plasmid pUB2380, is IS91-like. It is an active 1.7-
kb insertion sequence that lacks terminal inverted repeats, displays insertion-site specificity …

The bacterial insertion sequence, IS911, is a member of the large IS3family. It transposes
using a mechanism known as Copy‐out–Paste‐in. This is a major transposition pathway as …

Copy‐out/paste‐in transposition is a major bacterial DNA mobility pathway. It contributes
significantly to the emergence of antibiotic resistance, often by upregulating expression of …
