Free energy perturbation review
When I first started using CHARMM over 20 years ago as a PhD student, I regularly came across references to Free Energy Perturbation (FEP); we even discussed it in the group as a possible technique that could be used for an aspect of our work, but the computational resources were lacking at the time to do the … See more To run an FEP calculation we need to start with a protein structure, ideally with a bound ligand of interest. The protein structure needs to be prepared so that missing atoms in the side chains are added, as well as … See more Any target with a well-defined binding site could be considered for an FEP simulation. During the MD-based FEP simulation, the ligand … See more One final thought. The underlying method is based on a molecular mechanics force field, and simulations are, therefore, reliant on the force field … See more When setting up an FEP experiment, start with what is known. Firstly, prepare the protein for the simulation, making sure that it resembles the … See more WebApr 14, 2024 · As with the two- and three-body energies, the distance convergence of the four-body HF+CABS energy varies depending on the electrostatic moments of the molecule: for ethane, the values stay between 0 and 0.05 kJ/mol, while for acetylene/c the energy first reaches a value of almost 0.5 kJ/mol at a cutoff of around 30 Å, and then it …
