Steered Molecular Dynamics
Steered molecular dynamics (SMD) induces unbinding of ligands and conformational changes in biomolecules on time scales accessible to molecular dynamics simulations. Time-dependent external forces are applied to a system, and the responses of the system are analyzed. SMD has already provided important qualitative insights into biologically relevant problems, as demonstrated here for application...
متن کاملSteered molecular dynamics investigations of protein function.
Molecular recognition and mechanical properties of proteins govern molecular processes in the cell that can cause disease and can be targeted for drug design. Single molecule measurement techniques have greatly advanced knowledge but cannot resolve enough detail to be interpreted in terms of protein structure. We seek to complement the observations through so-called Steered Molecular Dynamics (...
متن کاملMultiple branched adaptive steered molecular dynamics.
Steered molecular dynamics, SMD, [S. Park and K. Schulten, J. Chem. Phys. 120, 5946 (2004)] combined with Jarzynski's equality has been used widely in generating free energy profiles for various biological problems, e.g., protein folding and ligand binding. However, the calculated averages are generally dominated by "rare events" from the ensemble of nonequilibrium trajectories. The recently pr...
متن کاملA virtual environment for steered molecular dynamics
A molecular dynamics simulation approximates the motion of atoms in a system of molecules over short intervals of simulated time, typically on the order of picoseconds to nanoseconds. Such simulations may run for days or weeks on a computer when used to investigate the dynamic behavior of small proteins in biological systems. By adding additional restraints, a simulation may be “steered” to obs...
متن کاملUnfolding of titin immunoglobulin domains by steered molecular dynamics simulation.
Titin, a 1-microm-long protein found in striated muscle myofibrils, possesses unique elastic and extensibility properties in its I-band region, which is largely composed of a PEVK region (70% proline, glutamic acid, valine, and lysine residue) and seven-strand beta-sandwich immunoglobulin-like (Ig) domains. The behavior of titin as a multistage entropic spring has been shown in atomic force mic...
