Most transposable elements move at low frequencies and insert into many different target
sites, displaying only modest or little target site-selectivity. The bacterial transposon Tn7 (B …

Tn7, a large bacterial transposon encodes 5 proteins required for its transposition. We report
a rapid and easy purification of one of these proteins, TnsB, from an overexpression strain …

The bacterial transposon Tn3 encodes a site-specific recombination system. The
recombination requires the product of tnpR, a gene previously identified as a repressor of …

Genes for (methyl) phenol degradation in Pseudomonas putida strain H (phl genes) are
located on the plasmid pPGH1. Adjacent to the phl catabolic operon we identified a cryptic …

We have generated recombinant plasmids in vivo between pHS1, a temperature-sensitive
replication mutant of pSC101 which codes for tetracycline (Tc) resistance, and pMB8 …

Tn 5 is a composite bacterial transposon that encodes a protein, transposase (Tnp), required
for movement of the transposon. The initial step in the transposition pathway involves …

We have identified and characterized the cis-acting sequences at the termini of the bacterial
transposon Tn7 that are necessary for its transposition. Tn7 participates in two kinds of …

The bacterial transposon Tn7 is distinguished by its capacity for high-frequency
transposition to a specific site in the Escherichia coli chromosome. tnsB is one of the five Tn7 …

Transposon Tn7 transposes at high frequency to a specific site, attTn7, in the Escherichia
coli chromosome. We devised a quantitative assay for Tn7 transposition in which Tn7-end …

The end sequences of the IS50 insertion sequence are known as the outside end (OE) and
inside end. These complex ends are related but nonidentical 19-bp sequences that serve as …
