What is the computationally most expensive part of a molecular dynamics simulation?

Typically, the most computationally expensive portion of a MD simulation is the evaluation of these long-range electrostatic interactions.

What is NVT simulation?

Canonical ensemble (NVT) In NVT, the energy of endothermic and exothermic processes is exchanged with a thermostat. A variety of thermostat algorithms are available to add and remove energy from the boundaries of an MD simulation in a more or less realistic way, approximating the canonical ensemble.

Does molecular dynamic simulations are important after docking?

The association with the costly but more accurate MD techniques provides significant complementary with docking. MD simulations can be used before docking since a series of “new” and broader protein conformations can be extracted from the processing of the resulting trajectory and employed as targets for docking.

What is NVE simulation?

I. Microcanonical (NVE) ensemble Molecular dynamics (MD) is the method of simulating kinetic and thermodynamic properties of molecular systems using Newton equations of motions. Usually numerical integration of equation of motions in MD is accomplished using Verlet algorithm.

How do molecular docking and molecular dynamics simulations contribute to drug discovery studies?

Molecular dynamics (MD) and related methods are close to becoming routine computational tools for drug discovery. This allows a more accurate estimate of the thermodynamics and kinetics associated with drug–target recognition and binding, as better algorithms and hardware architectures increase their use.

How does molecular mechanics work?

Molecular Mechanics is a computational method that computes the potential energy surface for a particular arrangement of atoms using potential functions that are derived using classical physics. These equations are known as a force-field. The bonds between molecules are treated as springs.

Why molecular dynamics studies are needed after performing docking?

All Answers (12) Hi, the purpose of MD after docking calculation is to confirm the poses found by docking. The MD calculation allows to establish if the most populated cluster from docking is also found by MD. In fact the static view provided by docking should be verify by using MD.
