Conformational conversion of proteins due to mutation

We present a potential-energy model that successfully reproduces the hydrogen bonding effect in proteins and can be used to represent well-defined secondary structures, both α-helices and β-sheets. We discuss the mechanism of conformational conversion, specifically between an α-helix and a β-hairpin, caused by sequence perturbation in monomer type. The thermodynamics and kinetics of the model were analyzed by the Monte Carlo simulation technique.
