A molecule that detects the length of DNA by using chain fluctuations
Kuni H. Iwasa, Ana Maria Florescu
A class of nucleosome remodeling motors translocate nucleosomes, to which they are attached, toward the middle of DNA chain in the presence of ATP during in vitro experiments. Such…
Free energy landscape and characteristic forces for the initiation of DNA unzipping
Ahmet Mentes, Ana Maria Florescu, Elizabeth Brunk +3
DNA unzipping, the separation of its double helix into single strands, is crucial in modulating a host of genetic processes. Although the large-scale separation of double-stranded…
Thermal and mechanical denaturation properties of a DNA model with three sites per nucleotide
Ana-Maria Florescu, Marc Joyeux
In this paper, we show that the coarse grain model for DNA, which has been proposed recently by Knotts, Rathore, Schwartz and de Pablo (J. Chem. Phys. 126, 084901 (2007)), can be a…
Comparison of kinetic and dynamical models of DNA-protein interaction and facilitated diffusion
Ana-Maria Florescu, Marc Joyeux
It has long been asserted that proteins like transcription factors may locate their target in DNA sequences at rates that surpass by several orders of magnitude the three-dimension…
Dynamical model of DNA-protein interaction: effect of protein charge distribution and mechanical properties
Ana-Maria Florescu, Marc Joyeux
The mechanical model based on beads and springs, which we recently proposed to study non-specific DNA-protein interactions [J. Chem. Phys. 130, 015103 (2009)], was improved by desc…
Description of non-specific DNA-protein interaction and facilitated diffusion with a dynamical model
Ana-Maria Florescu, Marc Joyeux
We propose a dynamical model for non-specific DNA-protein interaction, which is based on the 'bead-spring' model previously developed by other groups, and investigate its propertie…
