Multiple active zones in hybrid QM/MM molecular dynamics simulations for large biomolecular systems.
A new QM/MM molecular dynamics approach that can deal with the dynamics of large real systems involving several simultaneous active zones is presented. Multiple, unconnected but interacting quantum regions are treated independently in an ordinary QM/MM approach but in a manner which converges to a unique simulation. The multiple active zones in the hybrid QM/MM molecular dynamics methodology (m...
متن کاملImproved model of hydrated calcium ion for molecular dynamics simulations using classical biomolecular force fields.
Calcium ions (Ca(2+) ) play key roles in various fundamental biological processes such as cell signaling and brain function. Molecular dynamics (MD) simulations have been used to study such interactions, however, the accuracy of the Ca(2+) models provided by the standard MD force fields has not been rigorously tested. Here, we assess the performance of the Ca(2+) models from the most popular cl...
متن کاملEnergy conservation in molecular dynamics simulations of classical systems.
Classical Newtonian dynamics is analytic and the energy of an isolated system is conserved. The energy of such a system, obtained by the discrete "Verlet" algorithm commonly used in molecular dynamics simulations, fluctuates but is conserved in the mean. This is explained by the existence of a "shadow Hamiltonian" H [S. Toxvaerd, Phys. Rev. E 50, 2271 (1994)], i.e., a Hamiltonian close to the o...
متن کاملMolecular dynamics simulations.
Molecular dynamics simulations have become a standard tool for the investigation of biomolecules. Simulations are performed of ever bigger systems using more realistic boundary conditions and better sampling due to longer sampling times. Recently, realistic simulations of systems as complex as transmembrane channels have become feasible. Simulations aid our understanding of biochemical processe...
متن کاملMolecular dynamics simulations
Large biological molecules are frequently represented by a single three-dimensional structure, but in reality, under physiological conditions, they are dynamic entities in constant motion. One important theoretical technique for analyzing both motions and energetics and the roles they play in macromolecular structure and function is a form of simulation termed molecular dynamics. The field of o...
