Transferrin-polycation conjugates as carriers for DNA uptake into cells. [PDF]
, 1990 We have developed a high-efficiency nucleic acid delivery system that uses receptor-mediated endocytosis to carry DNA macromolecules into cells. We accomplished this by conjugating the iron-transport protein transferrin to polycations that bind nucleic ...

An expanded view of bacterial DNA replication [PDF]
Proceedings of the National Academy of Sciences, 2002 A protein-interaction network centered on the replication machinery of Bacillus subtilis was generated by genome-wide two-hybrid screens and systematic specificity assays. The network consists of 91 specific interactions linking 69 proteins.

Blood Metagenome in Health and Psoriasis
Frontiers in Medicine, 2020 A survey and analytical assessment of the results of fundamental works on studying blood metagenome (set of all non-human DNA) is carried out. All works on determining bacterial DNA concentration in the whole blood of healthy people are reviewed ...

Hyperchromicity and Strand Separation in Bacterial DNA
Biophysical Journal, 1962 Studies of the per cent of strand separation of N(14)-N(15) hybrid coli DNA heated to various temperatures in formaldehyde have shown that the process of strand separation is a function of temperature and formaldehyde concentration and is directly related to the measured hyperchromicity.

, 2017 Under supercoiling constraints, naked DNA, such as a large part of bacterial DNA, folds into braided structures called plectonemes. The double-helix can also undergo local structural transitions, leading to the formation of denaturation bubbles and other

Translocation of DNA across bacterial membranes [PDF]
Microbiological Reviews, 1994 DNA translocation across bacterial membranes occurs during the biological processes of infection by bacteriophages, conjugative DNA transfer of plasmids, T-DNA transfer, and genetic transformation. The mechanism of DNA translocation in these systems is not fully understood, but during the last few years extensive data about genes and gene products ...

Oral bacterial DNA findings in pericardial fluid
Journal of Oral Microbiology, 2014 Background: We recently reported that large amounts of oral bacterial DNA can be found in thrombus aspirates of myocardial infarction patients. Some case reports describe bacterial findings in pericardial fluid, mostly done with conventional culturing ...
