This tutorial sets out to demonstrate that the standard binding free energy of a protein:ligand complex can be determined accurately by means of restrained computer simulations. In the tutorial, calculation of the contribution due to restraints follows two distinct routes, an alchemical one and a geometrical one. The methodology is illustrated by the association of a small, proline-rich
Molecular dynamics of a protein // “It’s an major histocompatibilty complex (mhc) protein. Molecular Dynamics Software is Gromacs and it is visualised with VMD. Both can …
ICM-Docking and chemistry module provides access to the chemical information and provides a unique set of tools for accurate individual ligand-protein docking, peptide-protein docking, and protein-protein docking, including interactive graphics tools.
The coordinates of the co-crystallized ligand caffeine were extracted to a separate PDB file, and used to generate the corresponding forcefield parameters in the Gromacs format (parameters are included in the Tutorial section of GPCR-ModSim).
The tutorial itself allows one to perform simulations of this ligand-protein system. The performance of our ABP implementation is compared against native GROMACSv5.0.5 and native GROMACSv5.1 for several numbers of compute cores.
Standard MD is impractical for describing ligand-protein tological malignancies.[19] The lead ligand (compound 3 of reference10) in complex with bromodomain 1 ofBRD4 is shown in Figure 2. A pair of RMSD CVs were chosen for the simulations. One CV is the RMSD between a subset of atoms in the ligand at its current (simulated) position and the Xray structure. The second CV is the RMSD …
energy of protein–ligand complexes and distinguish strong binders from weak ones. In several recent researches, the protein–ligand rupt ure force obtained from SMD simulations was used as a measurement of the binding energy: the larger the rupture force of the receptor–ligand system is, the

For each of 50 independent starting configurations, the ligand was randomly positioned and oriented with a 1.5 nm solvent layer separating the outer edges of protein and ligand. MARTINI water and sufficient ions were added to neutralize the system. Each simulation was carried out for 500 ns using a time step of 20 fs with GROMACS

This tutorial uses GROMACS version 3.3.1 (Tsjerk A. Wassenaar). Another lysozyme tutorial – focused on details of the topology and explaining the ins and outs of each preparation step, designed for GROMACS 2018 (Justin A. Lemkul) Protein-Ligand Systems. Protein-ligand complex (T4 lysozyme) – an example of a protein-ligand/drug system, with focus on proper topology handling and parameterization
Basic knowledge of Gromacs is assumed, but feel free to ask during the tutorial if you have not used Gromacs earlier. For the official VMD tutorials, all input data is provided. For other exercises, it is possible to do them using your own simulation results, or using a provided trajectory of a large membrane protein. There is a lot of material, and if you are new to VMD, it is not likely that
Abstract This tutorial sets out to demonstrate the application of numerical simulations to the calculation of the standard binding free energy of a protein:ligand complex.
