手性折叠均聚物的规范场理论及其在折叠蛋白质中的应用
A Gauge Field Theory of Chirally Folded Homopolymers with Applications to Folded Proteins
摘要：
我们结合规范不变性与非本征弦几何的原则，开发一个晶格模型，可以用来从理论上描述手性，无支链的均聚物的性质。我们发现，在其低温阶段的模型是在相同的普适性类与蛋白质的存储在蛋白质数据库中，在这个意义上的紧凑性指数。我们应用该模型来分析折叠蛋白质的各种统计方面。奇怪的是，我们发现它可以产生与蛋白质数据库中的数据非常匹配的结果。
英文摘要：
We combine the principle of gauge invariance with extrinsic string geometry to develop a lattice model that can be employed to theoretically describe properties of chiral, unbranched homopolymers. We find that in its low temperature phase the model is in the same universality class with proteins that are deposited in the Protein Data Bank, in the sense of the compactness index. We apply the model to analyze various statistical aspects of folded proteins. Curiously we find that it can produce results that are a very good good match to the data in the Protein Data Bank.
