摘要Spider silk exhibits two excellent mechanical features, toughness and extensibility In recent years, considerable investigations have been focused on it. The understanding of spider silk protein is significant for the bionic silk. In this article, we study the force extension property of spider silk proteins as the function of the amino acid compositions for major and minor ampullate glands of typical Araneid orb weaver, as well as one artificial spider silk by Monte Carlo simulation. The results are also compared with a designed protein whose amino acid composition is uniform. It shows clearly that the major and minor ampullate gland proteins are much tougher than the designed protein, and the artificial protein as a model of a nature spider silk do have good mechanical properties. Our simulation reveals that the mechanical property of a spider silk protein is dependent on amino acid composition and the composition of spider silk protein is an excellent result of natural evolution.
