Homologous recombination is one of the key mechanisms responsible for the repair of DNA
double-strand breaks. Recombinational repair normally requires a battery of proteins, each …

Two pathways for DNA recombination, AddAB (RecBCD-like) and RecRO, were identified in
Helicobacter pylori, a pathogenic bacterium that colonizes human stomachs resulting in a …

Recombination is a fundamental mechanism for the generation of genetic variation.
Helicobacter pylori strains have different frequencies of intragenomic recombination, arising …

Helicobacter pylori is a genetically diverse bacterial species, owing in part to its natural
competence for DNA uptake that facilitates recombination between strains. Inter‐strain DNA …

Helicobacter pylori is a bacterial pathogen colonizing half of the world's human population. It
has been implicated in a number of gastric diseases, from asymptomatic gastritis to cancer. It …

Background Extensive genetic diversity and rapid allelic diversification are characteristics of
the human gastric pathogen Helicobacter pylori, and are believed to contribute to its ability …

The human gastric pathogen Helicobacter pylori encounters frequent oxidative and acid
stress in its specific niche, and this causes bacterial DNA damage. H. pylori exhibits a very …

Helicobacter pylori populations recovered from the human stomach display extensive
recombination and quasispecies development, and this suggests frequent exchange of DNA …

All organisms have pathways that repair the genome, ensuring their survival and that of their
progeny. But these pathways also serve to diversify the genome, causing changes at the …

The generation of a RecA filament on single-stranded DNA is a critical step in homologous
recombination. Two main pathways leading to the formation of the nucleofilament have been …
