Computational modeling of biological systems is challenging because of the multitude of spatial and temporal scales involved. Replacing atomistic detail with lower resolution, coarse grained (CG), beads has opened the way to simulate large-scale biomolecular processes on time scales inaccessible to all-atom models. We provide an overview of some of the more popular CG models used in biomolecular applications to date, focusing on models that retain chemical specificity. A few state-of-the-art examples of protein folding, membrane protein gating and self-assembly, DNA hybridization, and modeling of carbohydrate fibers are used to illustrate the power and diversity of current CG modeling.

生物分子模拟中粗粒度的力量。


由于涉及多种空间和时间尺度，生物系统的计算建模具有挑战性。珠子用较低分辨率的粗粒度 (CG) 取代原子细节，为在全原子模型无法达到的时间尺度上模拟大规模生物分子过程开辟了道路。我们概述了迄今为止在生物分子应用中使用的一些更流行的 CG 模型，重点关注保留化学特异性的模型。使用蛋白质折叠、膜蛋白门控和自组装、DNA 杂交以及碳水化合物纤维建模的一些最先进的示例来说明当前 CG 建模的力量和多样性。
