了解病毒衣壳蛋白围绕其基因组组装的途径可以确定作为潜在药物靶点的关键中间体。在这项工作中，我们使用计算机模拟来表征组装在广泛的衣壳蛋白质-蛋白质相互作用强度和溶液离子强度。我们发现，组装途径可以分为两类，其中中间体是主要有序或无序。我们的研究结果表明，估计蛋白质-蛋白质和蛋白质-基因组结合亲和力可能足以预测哪种途径发生。此外，计算出的相图表明，知识的主导组装途径及其与控制参数的关系，可以确定最佳的策略，以阻止或重定向组装，以阻止感染。最后，模拟轨迹的分析表明，这两类组装途径可以区分在单分子荧光相关光谱或批量时间分辨小角度X射线散射实验。
Understanding the pathways by which viral capsid proteins assemble around their genomes could identify key intermediates as potential drug targets. In this work we use computer simulations to characterize assembly over a wide range of capsid protein-protein interaction strengths and solution ionic strengths. We find that assembly pathways can be categorized into two classes, in which intermediates are either predominantly ordered or disordered. Our results suggest that estimating the protein-protein and the protein-genome binding affinities may be sufficient to predict which pathway occurs. Furthermore, the calculated phase diagrams suggest that knowledge of the dominant assembly pathway and its relationship to control parameters could identify optimal strategies to thwart or redirect assembly to block infection. Finally, analysis of simulation trajectories suggests that the two classes of assembly pathways can be distinguished in single molecule fluorescence correlation spectroscopy or bulk time resolved small angle x-ray scattering experiments.
