IS629 is 1,310 bp in length with a pair of 25-bp imperfect inverted repeats at its termini. Two
partially overlapping open reading frames, orfA and orfB, are present in IS629, and two …

The bacterial transposon Tn 917 inserts preferentially in the terminus region of some
members of the Firmicutes. To determine what molecular process was being targeted by the …

The occupation of the ς 54-dependent Pu promoter of Pseudomonas putida by the
integration host factor (IHF) under different growth conditions has been monitored in its …

The proteins expressed by insertion sequence IS911, a member of the widespread IS3
family of elements, have been analyzed. The results indicate that three major species are …

We analyzed the target preferences of a Tn 3 family transposon Tn 4652. Alignment of 93
different insertion sites revealed a consensus sequence which resembles that of Tn 3 …

Excision from the donor DNA molecule is the first step in conjugative transposition of Tn916
and is followed by circularization of the transposon and its transfer to a new host. We have …

Conjugative transposition of transposon Tn916 has been shown to proceed by excision of
the transposon in the donor strain and insertion of this element in the recipient. This process …

IS91 displays a number of characteristics unique among insertion sequence (IS) elements,
suggesting that it transposes by a novel mechanism called rolling‐circle (RC) transposition …

PIF-like transposable elements are members of the PIF/Harbinger superfamily of DNA
transposons found in the genomes of many plants, animals, and fungi. The evolution of the …

Conjugative plasmid transfer systems have been well studied, but very little is known about
the recipient factors that control horizontal transmission. A self-transmissible IncP-9 …
