Mechanisms of DNA-mediated allostery

M Segers, A Voorspoels, T Sakaue, E Carlon - Physical Review Letters, 2023 - APS
Proteins often regulate their activities via allostery—or action at a distance—in which the
binding of a ligand at one binding site influences the affinity for another ligand at a distal site …

Asymmetric Periodic Boundary Conditions for All-Atom Molecular Dynamics and Coarse-Grained Simulations of Nucleic Acids

R Erban, Y Togashi - The Journal of Physical Chemistry B, 2023 - ACS Publications
Periodic boundary conditions are commonly applied in molecular dynamics simulations in
