2D Plot and 3D Visualization of Protein-Ligand and Protein-Protein Interactions


Intermolecular interactions are weak bonds formed due to electron sharing between two or more atoms to hold a molecule together. In molecular modelling or computer-aided drug designing (CADD), intermolecular interaction studies are performed to analyze the stability/energy of docking molecules. This video tutorial demonstrates two-dimensional (2D) plot and three-dimensional (3D) molecular visualization of protein-ligand and protein-protein inter-molecular interactions using LigPlot+/LigPlus tool. LigPlot+ is a successor of original LigPlot program. The protein-ligand inter-molecular interactions are computed using LigPlot program and protein-protein or domain-domain inter-molecular interactions using DimPlot program. Moreover, the interactive 3D molecular visualization of the computed result can be viewed using RasMol or PyMOL. List of softwares used in this tutorial are LigPlot+, LigPlus, RasMol, PyMOL, and JDK.
