The bacteriophage genome undergoes a succession of intracapsid phase transitions upon DNA ejectionAmélie Leforestier
Laboratoire de Physique des Solides, Centre National de la Recherche Scientifique UMR 8502, Universite Paris Sud, Orsay, France
J Mol Biol 396:384-95. 2010..These structures suggest a mechanism in which defects of the full capsid would initiate the ejection and introduce the necessary fluidity to relax the constrained mosaic crystal to let the genome start flowing out of the capsid...
Role of histone tails in the conformation and interactions of nucleosome core particlesAurelie Bertin
Laboratoire de Physique des Solides, CNRS UMR 8502, Bat 510, Universite Paris Sud, 91405 Orsay
Biochemistry 43:4773-80. 2004..The attractive interactions do not emerge in the absence of the tails, which validates the proposed hypothesis...

Laboratoire de Physique des Solides, Universite Paris Sud, 91405 Orsay Cedex, France
Biophys J 84:2570-84. 2003..These concentrations cover the concentration of the living cell...
Salt-induced conformation and interaction changes of nucleosome core particlesStéphanie Mangenot
Laboratoire de Physique des Solides, Bat 510, Universite Paris Sud, 91405 Orsay Cedex, France
Biophys J 82:345-56. 2002..We discuss how the coupling of these two phenomena may be of biological relevance...
Structure of toroidal DNA collapsed inside the phage capsidAmélie Leforestier

Protein-DNA interactions determine the shapes of DNA toroids condensed in virus capsidsAmélie Leforestier
Laboratoire de Physique des Solides, Centre National de la Recherche Scientifique UMR 8502, Universite Paris Sud, Orsay, France
Biophys J 100:2209-16. 2011..Such attractive interactions seem to be specific to the PEG condensation process and are not observed in the case of spermine-induced DNA condensation...
Contribution of cryoelectron microscopy of vitreous sections to the understanding of biological membrane structureAmélie Leforestier
Laboratoire de Physique des Solides, Centre National de la Recherche Scientifique, Unité Mixte de Recherche 8502, Universite Paris Sud XI, 91405 Orsay Cedex, France
Proc Natl Acad Sci U S A 109:8959-64. 2012..Imaging the cell in its native hydrated state can now be done in the nanometer resolution range, which should open unique routes for investigating structure-function relationships...
Are liquid crystalline properties of nucleosomes involved in chromosome structure and dynamics?Françoise Livolant
Laboratoire de Physique des Solides, Bat 510, Universite Paris Sud, 91405 Orsay Cedex, France
Philos Trans A Math Phys Eng Sci 364:2615-33. 2006..Ordered phases are also found in the aggregates. We also discuss whether these condensed phases of nucleosomes may be relevant from a biological point of view...
