Integrated self‐transmissible elements called conjugative transposons have been found in
many different bacteria, but little is known about how they excise from the chromosome to …

NBU1 is a 10.3-kbp integrated Bacteroides element that can be induced to excise from the
chromosome and can be mobilized to a recipient by trans-acting functions provided by …

The Tn 552 transposase, a member of the DDE superfamily of transposase and retroviral
integrase proteins, has been expressed in soluble form. The purified protein performs …

Transposable genetic elements have adopted two major strategies for their displacement
from one site to another within and between genomes. One involves passage through an …

A cell-free system is described that accomplishes an unusual type of transposition/
recombination involving the bacterial insertion sequence IS911. Using a plasmid substrate …

Phage integrases are enzymes that catalyze unidirectional site-specific recombination
between the attachment sites of phage and host bacteria, attP and attB, respectively. We …

Site‐specific recombinases of the integrase family share limited amino‐acid‐sequence
similarity, but use a common reaction mechanism to recombine distinct DNA target sites …

Few nonviral techniques exist for efficient and stable eukaryotic gene transfer and fewer still
are broadly useful in both cell culture and whole-organism applications. ɸC31 integrase, a …

Mammalian Markup Recombination techniques utilizing the Cre and Flp systems are now
accepted as standard procedures in genome engineering, particularly in manipulating …

Chloramphenicol resistance in Clostridium perfringens and Clostridium difficile is often
encoded by catP genes located within the 6.3 kb integrative mobilizable elements Tn4451 …
