WebOct 17, 2016 · DNA uptake proceeded at a velocity of ∼80 bp⋅s −1 up to external forces of 50 pN . In contrast, DNA uptake was reversible at forces of ∼20 pN in the Gram-negative H. pylori . The velocity of DNA uptake, however, was considerably faster with 1.3 kbp⋅s −1 at 10 pN. H. pylori has adapted a type IV secretion system for DNA uptake .

WebWe go on to show that DNA-uptake pili bind to chitinous surfaces and are required for chitin colonization under flow, and that pili capable of self-interaction connect cells on chitin within dense pili networks. Our results suggest a model whereby DNA-uptake pili function to promote inter-bacterial interactions during surface colonization. WebEfficient DNA uptake in Neisseria and H. influenzae requires a species-specific DNA uptake sequence about 10 nucleotides long (13, 14). The genomes of these bacteria are enriched for their respective uptake sequences, favoring the uptake of homospecific …
