Natural DNA uptake by Escherichia coli. [PDF]
PLoS ONE, 2012 Escherichia coli has homologues of the competence genes other species use for DNA uptake and processing, but natural competence and transformation have never been detected.

A Halocin Promotes DNA Uptake in Haloferax mediterranei [PDF]
Frontiers in Microbiology, 2019 Halocins are antimicrobial peptides or proteins that are produced by halophilic archaea. Although their function in inhibiting the growth of closely related haloarchaeal strains is well known, other physiological functions of halocins have also been ...

Dialects of the DNA uptake sequence in Neisseriaceae. [PDF]
PLoS Genetics, 2013 In all sexual organisms, adaptations exist that secure the safe reassortment of homologous alleles and prevent the intrusion of potentially hazardous alien DNA. Some bacteria engage in a simple form of sex known as transformation.

Cj0683 Is a Competence Protein Essential for Efficient Initialization of DNA Uptake in Campylobacter jejuni [PDF]
Biomolecules, 2023 C. jejuni is an important food-borne pathogen displaying high genetic diversity, substantially based on natural transformation. The mechanism of DNA uptake from the environment depends on a type II secretion/type IV pilus system, whose components are ...

Genome-wide analysis of DNA uptake across the outer membrane of naturally competent Haemophilus influenzae [PDF]
iScience, 2021 Summary: The genomes of naturally competent Pasteurellaceae and Neisseriaceae have many short uptake sequences (USS), which allow them to distinguish self-DNA from foreign DNA.

Detection of exogenous DNA uptake by murine dendritic cells [PDF]
STAR Protocols, 2022 Summary: This protocol has been developed to measure exogenous DNA uptake by murine dendritic cells (DCs) using supernatant containing cellular debris, which allows for DNA uptake in the absence of transfection reagents.

Endocytosis-like DNA uptake by cell wall-deficient bacteria [PDF]
Nature Communications, 2022 Horizontal gene transfer in bacteria can occur through mechanisms such as conjugation, transduction and transformation, which facilitate the passage of DNA across the cell wall. Here, Kapteijn et al. show that cell wall-deficient bacteria can take up DNA

The molecular basis of FimT-mediated DNA uptake during bacterial natural transformation [PDF]
Nature Communications, 2022 Many bacteria can take up exogenous DNA, in a process that often requires surface appendages composed of thousands of protein subunits called pilins. Here, Braus et al.

A conserved nuclease facilitates environmental DNA uptake. [PDF]
Nucleic Acids ResAbstract Bacteria acquire new traits through the uptake of genetic material from the environment, a process requiring DNA processing. However, the molecular inventory mediating this process is far from being completely understood. Here, we identify YhaM in Bacillus subtilis as a conserved 3′-deoxyribonuclease essential for the uptake and
