Details
The association of ligands to proteins is regulated by interactions between the molecule and protein residues at the binding site, which can be located in a binding pocket or on the protein surface.
Such interactions can directly modulate protein functions and conformations, with possible implications for biophysical processes such as protein co-crystallisation [1-3] or selective molecular design [4].
Computational methods to study these systems, as molecular dynamics simulations (MDs) which can range from atomistic to coarse-grained resolution [5,6], provide insights into the mechanisms, kinetics and thermodynamics underlying protein-ligand complex formation.
Here, it will be discussed how these supramolecular structures may be described by these approaches, highlighting characteristic fingerprints and key models for interactions.
