Peptides mediate up to 40% of protein interactions, their high specificity and ability to bind in places where small molecules cannot make them potential drug candidates. However, predicting peptide-protein complexes remains more challenging than protein-protein or protein-small molecule interactions, in part due to the high flexibility peptides have. In this review we look at the advances in docking, molecular simulations, and machine learning to tackle problems related to peptides such as predicting structures, binding affinities or even kinetics. We specifically focus on explaining the number of docking programs and force fields used in molecular simulations, so a prospective user can have an educated guess as to why choose one modeling tool or another to address their scientific questions.
