在球状蛋白质的折叠和展开过渡的非相互作用的局部结构模型，其配方在前面的文件中给出，被施加到蛋白质的二维晶格模型的分析。蛋白质的晶格模型是一种理论工具，旨在研究折叠和去折叠转变的物理力学方面。用Monte Carlo模拟方法研究了它的动力学。的非相互作用的局部结构模型再现的平衡性质的晶格模型之前得到的计算机模拟非常好，当的特异性的长程相互作用是强的。这一观察结果表明，非相互作用局部结构模型的基本假设是等价的分子内相互作用的强特异性的假设。通过假设这种强特异性，可以强调折叠和展开过渡的正确主要路径。通过非相互作用局部结构模型讨论了局部结构沿着晶格模型中最可能的折叠路径生长和/或沿着合并的方式。
The noninteracting local-structure model of the folding and unfolding transition in globular proteins, the formulation of which was given in the preceding paper, is applied to the analysis of the 2-dimensional lattice model of proteins. The lattice model of proteins is a theoretical tool designed to study the statistical-mechanical aspect of the folding and unfolding transition. Its dynamics were studied by a method of Monte Carlo simulation. The noninteracting local-structure model reproduces the equilibrium properties of the lattice model obtained previously by computer simulation remarkably well, when the specificity of the long-range interactions is strong. This observation indicates that the basic assumption of the noninteracting local-structure model is equivalent to the assumption of strong specificity of intramolecular interactions. By assuming this strong specificity, the correct main paths of folding and unfolding transition can be emphasized. The way local structures grow and/or merge along the most probable path of folding in the lattice model is discussed by the noninteracting local-structure model.
