The novel coronavirus pandemic has collectively re-focused the research community towards a collaborative investigation of the SARS-CoV-2 virus and discovery of the mechanisms supporting COVID19 manifestation in humans. Research on the novel coronavirus has progressed with unprecedented speed due, in large part, the rapid determination of the SARS-CoV-2 genome and proteome. Promisingly, many computational approaches have also been deployed to increase our understanding of SARS-CoV-2, including the prediction of protein function, three-dimensional protein structure, and possible therapeutic targets for existing small inhibitory molecules. Given that the Spike protein from the original SARS coronavirus, SARS-CoV, is known to interact with the human Angiotensin-Converting Enzyme 2 (hACE2), much of the current research effort is focused to better characterize the SARS-CoV-2 Spike protein and its putative interaction with the ACE2 protein; a critical protein-protein interaction necessary for host infection. Similar efforts are being made to understand the functional and evolutionary characteristics of the SARS-CoV-2 proteome, including the determination of evolutionary conserved functional regions between related viruses to inform the use of anti-viral therapeutics. Given the unique infectivity characteristics of this novel coronavirus, the need for an effective strategy of anti-viral development is pressing. The long viral incubation period, during which an individual is simultaneously contagious and asymptomatic, has resulted in rapid global proliferation. Leveraging what is known from the original SARS-CoV outbreak, circa. 2003, and related viral families, this proposal contributes to our understanding of the viral inter-species protein interaction network. Together with Zim Corporation, a Canadian company with software and peptide biopharmaceutical experience, our cross-disciplinary team will use algorithms co-developed by co-applicants Biggar and Green to study the novel coronavirus and to produce novel peptide-based anti-viral drugs that antagonize interactions deemed critical to the virus-host interaction. Further, not only will this research develop potential anti-viral peptides for COVID19 treatment, but also establish an innovative resource for anti-viral peptide development as new viruses are introduced to the human population.

新型冠状病毒大流行使研究界重新集中精力，共同研究SARS-CoV-2病毒，并发现支持covid - 19在人类中表现的机制。对新型冠状病毒的研究取得了前所未有的进展，这在很大程度上是由于快速确定了SARS-CoV-2基因组和蛋白质组。有希望的是，许多计算方法也被用于增加我们对SARS-CoV-2的理解，包括预测蛋白质功能、三维蛋白质结构以及现有小抑制分子的可能治疗靶点。鉴于已知来自SARS原始冠状病毒SARS- cov的刺突蛋白与人血管紧张素转换酶2 （hACE2）相互作用，目前的大部分研究工作都集中在更好地表征SARS- cov -2刺突蛋白及其与ACE2蛋白的推定相互作用；宿主感染所必需的关键蛋白质-蛋白质相互作用。正在进行类似的努力，以了解SARS-CoV-2蛋白质组的功能和进化特征，包括确定相关病毒之间的进化保守功能区域，以便为使用抗病毒治疗提供信息。鉴于这种新型冠状病毒独特的传染性特征，迫切需要一种有效的抗病毒开发策略。长期的病毒潜伏期，在此期间，一个人同时具有传染性和无症状，导致全球迅速扩散。利用从最初的sars冠状病毒爆发中所知道的，大约。这一建议有助于我们对病毒种间蛋白相互作用网络的理解。我们的跨学科团队将与拥有软件和多肽生物制药经验的加拿大公司Zim Corporation合作，使用由
