Structural snapshots of Xer recombination reveal activation by synaptic complex remodeling and DNA bending [PDF]
Bacterial Xer site-specific recombinases play an essential genome maintenance role by unlinking chromosome multimers, but their mechanism of action has remained structurally uncharacterized. Here, we present two high-resolution structures of Helicobacter

The emerging role of recombineering in microbiology
: Recombineering is a valuable technique for generating recombinant DNA in vivo, primarily in bacterial cells, and is based on homologous recombination using phage-encoded homologous recombinases, such as Redαβγ from the lambda phage and RecET from the ...

Gated rotation mechanism of site-specific recombination by ϕC31 integrase [PDF]
Integrases, such as that of the Streptomyces temperate bacteriophage ϕC31, promote site-specific recombination between DNA sequences in the bacteriophage and bacterial genomes to integrate or excise the phage DNA.

A Topological Characterization Of Knots and Links Arising From Site-Specific Recombination [PDF]
We develop a topological model of knots and links arising from a single (or multiple processive) round(s) of recombination starting with an unknot, unlink, or (2,m)-torus knot or link substrate.

Modeling Gliomas Using Two Recombinases [PDF]
Abstract Development of animal models to investigate the complex ecosystem of malignant gliomas using the Cre/loxP recombination system has significantly contributed to our understanding of the molecular underpinnings of this deadly disease.

Machines on Genes: Enzymes that Make, Break and Move DNA and RNA [PDF]
As the vital information repositories of the cell, the nucleic acids DNA and RNA pose many challenges as enzyme substrates. To produce, maintain and repair DNA and RNA, and to extract the genetic information that they encode, a battery of remarkable ...

The dif/Xer recombination systems in proteobacteria. [PDF]
In E. coli, 10 to 15% of growing bacteria produce dimeric chromosomes during DNA replication. These dimers are resolved by XerC and XerD, two tyrosine recombinases that target the 28-nucleotide motif (dif) associated with the chromosome's replication ...

High-performance chemical- and light-inducible recombinases in mammalian cells and mice
The availability of high performance recombinases with low basal activity and high dynamic range is limited. Here the authors present a library of over 20 orthogonal split recombinases that can be induced by small molecules, light and temperature in vivo.
