序贯Monte Carlo方法评价突变对COVID-19刺突蛋白结构的影响

Assessing the impacts of mutations to the structure of COVID-19 spike protein via sequential Monte Carlo

Samuel W. K. Wong

摘要:

蛋白质在促进2019年新型冠状病毒的传染性方面发挥着关键作用。一种特定的刺突蛋白使这种病毒能够与人类细胞结合,因此对其三维结构的透彻理解对于开发有效的治疗干预措施至关重要。然而,由于突变,其结构可能会随着时间的推移而继续演变。在本文中,我们使用数据科学的角度来研究由于其氨基酸序列中的持续突变而产生的潜在结构影响。要做到这一点,我们确定了一个关键的蛋白质片段,并应用顺序蒙特卡罗采样方法来检测可能的变化,为不同的氨基酸序列的低能量构象的空间。这种计算方法可以进一步了解这种蛋白质的结构,并补充实验室的努力。

英文摘要:

Proteins play a key role in facilitating the infectiousness of the 2019 novel coronavirus. A specific spike protein enables this virus to bind to human cells, and a thorough understanding of its 3-dimensional structure is therefore critical for developing effective therapeutic interventions. However, its structure may continue to evolve over time as a result of mutations. In this paper, we use a data science perspective to study the potential structural impacts due to ongoing mutations in its amino acid sequence. To do so, we identify a key segment of the protein and apply a sequential Monte Carlo sampling method to detect possible changes to the space of low-energy conformations for different amino acid sequences. Such computational approaches can further our understanding of this protein structure and complement laboratory efforts.
