Abstract:
The application of molecular dynamics simulations to study the folding and dynamics of peptides has attracted a lot of interest in the last couple of decades. Following the successful prediction of the folding of several proteins using molecular simulation, foldable peptides emerged as a favourable system mainly due to their application in improving protein structure prediction methods and in drug design studies. However, their performance is inherently linked to the accuracy of the empirical force fields used in the simulations, whose optimisation and validation is of paramount importance. Here we review the most important findings in the field of molecular peptide simulations and highlight the significant advancements made over the last twenty years. Special reference is made on the simulation of disordered peptides and the remaining challenge to find a force field able to describe accurately their conformational landscape.
