DNA condensation in bacteria: Interplay between macromolecular crowding and nucleoid proteins

R De Vries - Biochimie, 2010 - Elsevier
The volume of a typical Eschericia coli nucleoid is roughly 104 times smaller than the
volume of a freely coiling linear DNA molecule with the same length as the E. coli genome …

Compaction of bacterial genomic DNA: clarifying the concepts

M Joyeux - Journal of Physics: Condensed Matter, 2015 - iopscience.iop.org
The unconstrained genomic DNA of bacteria forms a coil, whose volume exceeds 1000
times the volume of the cell. Since prokaryotes lack a membrane-bound nucleus, in sharp …

Crenarchaeal chromatin proteins Cren7 and Sul7 compact DNA by inducing rigid bends

RPC Driessen, H Meng, G Suresh… - Nucleic acids …, 2013 - academic.oup.com
Archaeal chromatin proteins share molecular and functional similarities with both bacterial

In vitro studies of DNA condensation by bridging protein in a crowding environment

SK Ramisetty, P Langlete, R Lale, RS Dias - International journal of …, 2017 - Elsevier
The macromolecules of the bacterial cell occupy 20–40% of the total cytosol volume, and
crowded environments have long been known to compact and stabilize DNA. Nevertheless …

Compaction of isolated Escherichia coli nucleoids: Polymer and H-NS protein synergetics

AS Wegner, K Wintraecken, R Spurio… - Journal of Structural …, 2016 - Elsevier
Escherichia coli nucleoids were compacted by the inert polymer polyethylene glycol (PEG)
in the presence of the H-NS protein. The protein by itself appears to have little impact on the …

Synergistic role of DNA-binding protein and macromolecular crowding on DNA condensation. An experimental and theoretical approach

SK Ramisetty, RS Dias - Journal of Molecular Liquids, 2015 - Elsevier
Genome packaging in prokaryotic cells is believed to be carried out by a combination of
DNA-binding proteins, crowding effects, and DNA supercoiling. Much is known about DNA …

Macromolecular Crowding and the Sizes of Neutral Flexible Polymer Chains: The Role of Colloids Sizes and Concentrations
