Abstract

AbstractMechanical extension of the ubiquitin with constant speed in five different directions is simulated on coarse‐grained Go‐like and all‐atom models. The anisotropy of the mechanical resistance of the protein is observed in agreement with experimental data. Differences and similarities between the results obtained for two models are discussed. It is shown that the unfolding begins from the rupture of contacts between residues located in the vicinity of points of the external load application.
