Evidence for a Xer/dif system for chromosome resolution in archaea. [PDF]
Homologous recombination events between circular chromosomes, occurring during or after replication, can generate dimers that need to be converted to monomers prior to their segregation at cell division.

Making serine integrases work for us [PDF]
DNA site-specific recombinases are enzymes (often associated with mobile DNA elements) that catalyse breaking and rejoining of DNA strands at specific points, thereby bringing about precise genetic rearrangements.

Uropathogenic Escherichia coli (UPEC) is the most common etiologic agent of uncomplicated urinary tract infection (UTI). An important mechanism of gene regulation in UPEC is phase variation that involves inversion of a promoter-containing DNA element via

The tyrosine-type site-specific DNA recombinase Cre recombines its target site, loxP, with high activity and specificity without cross-recombining the target sites of highly related recombinases. Understanding how Cre achieves this precision is key to be

Tyrosine Recombinase Retrotransposons and Transposons
ABSTRACT Retrotransposons carrying tyrosine recombinases (YR) are widespread in eukaryotes. The first described tyrosine recombinase mobile element, DIRS1, is a retroelement from the slime mold Dictyostelium discoideum . The YR elements are bordered by terminal repeats related to their replication via free

Promoter Orientation of Prokaryotic Phase-variable Genes by PCR
One major mechanism of phase variable gene expression in prokaryotes is through inversion of the promoter element for a gene or operon. This protocol describes how to detect the promoter orientation of a phase-variable gene by PCR.

FtsK-dependent dimer resolution on multiple chromosomes in the pathogen Vibrio cholerae. [PDF]
Unlike most bacteria, Vibrio cholerae harbors two distinct, nonhomologous circular chromosomes (chromosome I and II). Many features of chromosome II are plasmid-like, which raised questions concerning its chromosomal nature.

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

Tyrosine phosphorylation stimulates activity of human RAD51 recombinase through altered nucleoprotein filament dynamics [PDF]
Significance Homologous recombination provides the most accurate means to repair genotoxic DNA lesions. It depends on the assembly of the RAD51 DNA strand exchange protein into a dynamic nucleoprotein filament. The c-Abl tyrosine kinase and its oncogenic counterpart BCR-ABL control RAD51 by phosphorylating tyrosine residues 54 and 315.
