摘　　要：Dear Editor,The spread of the SARS-CoV-2 variants,especially the global variants of concern(VOCs),could seriously dampen our efforts to tackle the COVID-19 pandemic.The SARS-CoV-2 spike protein recognizes the host angiotensin-converting enzyme 2(ACE2)via its receptor-binding domain(RBD)to mediate viral entry into the cells.Several notorious mutations have been identified in the spike RBD of the VOCs.For example,B.1.1.7(Alpha),B.1.351(Beta),and P.1(Gamma)all contain the N501Y mutation,which increases the binding affinity for human ACE2 and confers higher infectivity in mice.
