Towards a molecular view of transcriptional control

K Zakrzewska, R Lavery - Current opinion in structural biology, 2012 - Elsevier
The accumulation of experimental data over recent years has fueled theoretical work on how
transcription factors (TFs) search for and recognise their DNA target sites, how they interact …

Exploring LacI–DNA dynamics by multiscale simulations using the SIRAH force field

MR Machado, S Pantano - Journal of chemical theory and …, 2015 - ACS Publications
The lac repressor protein (LacI) together with its target regulatory sequence are a common

Interplay of Protein and DNA Structure Revealed in Simulations of the lac Operon

L Czapla, MA Grosner, D Swigon, WK Olson - PLoS One, 2013 - journals.plos.org
The E. coli Lac repressor is the classic textbook example of a protein that attaches to widely
spaced sites along a genome and forces the intervening DNA into a loop. The short loops …

Role of microscopic flexibility in tightly curved DNA

M Taranova, AD Hirsh, NC Perkins… - The Journal of Physical …, 2014 - ACS Publications
The genetic material in living cells is organized into complex structures in which DNA is
subjected to substantial contortions. Here we investigate the difference in structure …

Insights into genome architecture deduced from the properties of short Lac repressor-mediated DNA loops

PJ Perez, WK Olson - Biophysical reviews, 2016 - Springer
Genomic DNA is vastly longer than the space allotted to it in a cell. The molecule must fold
with a level of organization that satisfies the imposed spatial constraints as well as allow for …
