我们建议对SARS-CoV-2刺突蛋白与可能的人类细胞受体之间的相互作用机制进行计算研究。特别是,我们利用我们新开发的数值方法,能够有效和有效地确定蛋白质表面各部分之间的互补关系。这一创新和通用的方法基于分子等电子密度面的2D Zernike多项式表示,允许快速和定量地评估相互作用的蛋白质之间的几何形状互补性,这在以前的方法中是不可行的。我们的结果表明SARS-CoV-2使用双重策略:除了已知的与血管紧张素转换酶2的相互作用外,病毒刺突蛋白还可以与上呼吸道细胞的唾液酸受体相互作用。
We propose a computational investigation on the interaction mechanisms between SARS-CoV-2 spike protein and possible human cell receptors. In particular, we make use of our newly developed numerical method able to determine efficiently and effectively the relationship of complementarity between portions of protein surfaces. This innovative and general procedure, based on the representation of the molecular isoelectronic density surface in terms of 2D Zernike polynomials, allows the rapid and quantitative assessment of the geometrical shape complementarity between interacting proteins, which was unfeasible with previous methods. Our results indicate that SARS-CoV-2 uses a dual strategy: in addition to the known interaction with angiotensin-converting enzyme 2, the viral spike protein can also interact with sialic-acid receptors of the cells in the upper airways.
