Analysis of protein-ligand interactions is a common task in computational biophysics. One way Discovery Studio can help is with the Show 2D Diagram and the Ligand Interaction tools, both located in the Protein-Ligand Interactions toolbar. 

These tools are designed to be highly interactive, ensuring that selections made in the 2D diagram are mirrored in the 'Molecule' window, and vice versa. This bi-directional functionality ensures a seamless and efficient workflow.

In this example, residue Leu221 was selected within the 2D Diagram, enabling us to swiftly identify the residue in the structure.
