All the CVs are implemented in the PLUMED plugin70 for GROMACS. Free energy reconstruction in the CV space. Bias-exchange metadynamics allows the free energy of a system to be reconstructed once the bias potentials become stable. This happens in our case after an estqauteilsiborfattihoensty...

Metadynamics is an atomistic simulation technique that allows, within the same framework, acceleration of rare events and estimation of the free energy of complex molecular systems. It is based on iteratively ‘filling’ the potential energy of the system by a sum of Gaussians centred along the ...

For GAFF 1.81, AM1-BCC charges [19] were derived with AmberTools 19 and ACPYPE [20] was used to convert the parameters to a Gromacs compatible format. CGenFF parameters were obtained using thehttps://cgenff.umaryland.eduwebserver [21]. Ionization states from the latest version of the ...
The Cu2+-bound and metal-free α-synuclein (1-17) peptides were simulated with the GROMOS 43A1 force field in the GROMACS package. There were six groups and each group was run for 500 ns in the physiological environment, giving a total of 3 μs. It was found that the Cu2+-bound ...
Computational Methods Simulations were performed in the GROMACS package12 version 4.5.5,14,13 using the GROMOS 53a6 force-field14 and the SPC water model15. We simulate the MspA pore using a similar modeling approach to the one we have previously described for alpha hemolysin16,17. We ...
Relative binding free energy calculations have become an integral computational tool for lead optimization in structure-based drug design. Classical alchemical methods, including free energy perturbation or thermodynamic integration, compute relative fre
