SARS-CoV-2 spike protein trimer (S3), as a component of the S3:M:E:encapsidated SARS coronavirus-2 genomic RNA: 7a:O-glycosyl 3a tetramer complex, binds to glycosylated angiotensin converting enzyme 2 (ACE2) associated with the human host cell plasma membrane (Zhang et al, 2020; Raghuvamsi et al, 2021; reviewed by Jackson et al, 2022). Glycosylation of both molecules is the most important factor in their interaction (reviewed by Reis et al, 2021; Shajahan et al, 2021; Gong et al, 2021). Spike binding to ACE2 also requires the presence of heparan sulfate (HS) on the cell surface, consistent with the formation of a ternary complex between S, ACE2, and heparan sulfate proteoglycans (HSPGs) (Kim et al, 2020; Zhang et al, 2020; Clausen et al, 2021; Liu et al, 2021; Yue et al, 2021; Bermejo-Jambrina et al, 2021).

In SARS-CoV-1 structural studies of the interaction between human ACE2 protein and the receptor-binding domain of S3 protein have identified key amino acid residues in both proteins responsible for their high-affinity interaction. These residues may be a key factor determining severity (and possibly human-to-human transmission) of SARS-CoV-1 (Li et al. 2003, 2005). The roles of S protein in viral binding to the host cell membrane and fusion of viral and host cell membranes and thus the central role of S protein in determining the host range and tissue tropisms of the virus are reviewed by Belouzard et al. (2012) and Jackson et al. (2022).
