For reference, the receptor-binding domain is only about 15% of the full spike protein, stretching from amino acid 332 to 523 (Figure 1). These are the carboxy-terminal, the n-terminal domain, the fusion peptide, and the carboxy-terminus of the S2 subunit. The intensity of the color shows the magnitude of reductions or promotions (Figure 3). N-terminal domain (NTD); receptor-binding domain (RBD); ... [+] carboxy-terminal domain (CTD); fusion peptid (FP); heptad repeat (HP); transmembrane and carboxy terminus (TM+CT) Garrett et al. When the spike protein or receptor-binding domain are targeted, the recognized structures are three-dimensional and yield different binding actions.
