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 …

The ampicillin resistance transposon, Tn3, is one of the most extensively studied and best
understood procaryotic transposable DNA elements. It is the prototype of a large class of …

The tnpR gene of transposon Tn3 encodes a site‐specific recombination enzyme that acts at
res, a DNA region adjacent to tnpR, to convert co‐integrate intermediates of interreplicon …

The complete nucleotide sequence of the transposon Tn3 and of 20 mutations which affect
its transposition are reported. The mutations, generated in vitro by random insertion of …

The transposase encoded by the tnpA gene of Tn3 is a protein specifically required for Tn3
transposition. We have purified it to homogeneity from an Escherichia coli strain containing a …

Deletions in transposon Tn7 either abolished transposition or reduced transposition
frequency. Except for a deletion in the right-hand terminus, these deletions could be …

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

The element IS50 encodes all Tn5 functions required for transposition and all regulatory
mechanisms. Bacterial transposon Tn5 encodes two proteins, transposase and the …

A central question concerning the mechanism of bacterial transposition is whether the
transposing element is duplicated during the recombination process. Early genetic and …

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 …
