A class II Tn3-type transposable element, designated Tn5393 and located on plasmid
pEa34 from streptomycin-resistant strain CA11 of Erwinia amylovora, was identified by its …

We describe a novel type of mercury resistance transposon, Tn5053, which was found in the
chromosome of a mercury-resistant Xanthomonas strain isolated from a mercury mine. An …

The integrase encoded by the integron of the transposon Tn21 can mediate the site‐specific
fusion of two plasmids if there is a recombination hot spot (59 bp element) in one of them …

A series of Tn7721-based mini-transposons (TnMax) has been developed which are
suitable for the targeting of cloned genes, shuttle mutagenesis, identification of protein …

In this study, a 498-bp dhfrXII gene coding for trimethoprim resistance was found inserted in
a cassette-like manner in the recombinationally active locus, the integron, borne on a …

Two different enteric plasmids of widely separate origins were observed to carry a new 15.3-
kb trimethoprim resistance transposon, Tn5086, also mediating resistance to mercuric ions …

Conjugative plasmids in bacteria bring about the transfer of DNA by cell contact between a
donor and a recipient (250). Naturally occurring conjugative plasmids transfer themselves …

Resolvases from Tnd-like transposons catalyse sitespecific recombination at res sites. Each
res site has 3 binding sites for resolvase, I, II, and III. The res sites in Tn3 and Tn21 have …

A novel transposon (Tn) mutagenesis system for Gram− non-enteric bacteria was developed
which allowed rapid and one-step cloning of the mutated region in Escherichia coli. The Tn …

Abstract A 12.4-kb plasmid, pTF-FC2, that was isolated from Thiobacillus ferrooxidans and
which is capable of replication in a wide range of Gram-negative bacteria, has been …
