| T52 | 0-7 | Sentence | denotes | Results |
| T53 | 9-82 | Sentence | denotes | Homology analysis of the spike proteins of SARS-CoVs and related Bat-CoVs |
| T54 | 83-202 | Sentence | denotes | Phylogenetic analysis of the spike protein sequences of SARS-CoV-2 and Bat-CoVs, SARS-CoV is shown in Figure 1(Fig. 1). |
| T55 | 203-490 | Sentence | denotes | The results are in agreement with recent reports of an independent introduction of SARS-CoV-2 from a Bat-CoV, different from the spillover which led to the introduction of SARS-CoV, being the Bat-CoV of Rhinolophus affinis the probable ancestor of this new virus (Wong et al., 2020[18]). |
| T56 | 491-607 | Sentence | denotes | Indeed, the sequences of the whole spike of this Bat-CoV and of SARS-CoV-2 share 97.7 % identity (Figure 1(Fig. 1)). |
| T57 | 608-742 | Sentence | denotes | More divergence is found however in the S1 subunit, particularly in the Receptor Binding Domain (RBD) of the different spike proteins. |
| T58 | 743-948 | Sentence | denotes | SARS-CoV and Bat-CoV from Rhinolophus sinicus (originally signaled as the most closely related virus to SARS-CoV-2) exhibit several amino acid substitutions and deletions in the RBD compared to SARS-CoV-2. |
| T59 | 949-1116 | Sentence | denotes | The RBD of Bat-CoV from Rhinolophus affinis, although more closely related to the one of SAS-CoV-2, also displayed several amino acid substitutions (Figure 2(Fig. 2)). |
| T60 | 1118-1161 | Sentence | denotes | Structural analysis of Spike-ACE2 complexes |
| T61 | 1162-1403 | Sentence | denotes | The crystal structures of the spike protein of SARS-CoV and homology models of Bat-CoV (accession number MG772933), Bat-CoV of Rhinolophus sinicus, and SARS-CoV-2 interacting with the putative binding domain site in human ACE2 were analyzed. |
| T62 | 1404-1476 | Sentence | denotes | The interaction pattern between the three viral spikes is quite similar. |
| T63 | 1477-1704 | Sentence | denotes | The main region of interaction with the putative cellular receptor counter-part is formed by fifteen residues ordered into a beta-sheet conformation surrounded by two capping loops (Figure 3(Fig. 3) and Supplementary Figure 1). |
| T64 | 1705-1926 | Sentence | denotes | Interestingly, sequence comparison between SARS-CoV-2 and SARS-CoV revealed that the residues present in the receptor-interacting motive are highly conserved with 70 % identity, sharing nine residues between both viruses. |
| T65 | 1927-2072 | Sentence | denotes | In the SARS-CoV RBD are present residues that allowed the interspecies infection, known as Y442, L472, N479, D480, and T487 (Lu et al., 2015[6]). |
| T66 | 2073-2225 | Sentence | denotes | However, in SARS-CoV-2, slight modification of some residues could improve the interaction with the human cellular receptor: L455, F486, Q493, and N501. |
| T67 | 2226-2359 | Sentence | denotes | In SARS-CoV, two main residues (479 and 487) have been associated to the recognition of the human ACE2 receptor (Lu et al., 2015[6]). |
| T68 | 2360-2455 | Sentence | denotes | These residues suffered a punctual mutation from civet to human, K479N and S487T (Li, 2013[5]). |
| T69 | 2456-2546 | Sentence | denotes | In the SARS-CoV-2, the residues corresponding to N479 correspond to Q493 and T487 to N501. |
| T70 | 2547-2659 | Sentence | denotes | These changes in the SARS-CoV-2 represent energetically favorable changes for the interaction with the receptor. |
| T71 | 2660-2821 | Sentence | denotes | The local environment present in the ACE2 receptor allows these mutations to produce a significant number of electrostatic stabilizing interactions (Table 1(Tab. |
| T72 | 2822-2826 | Sentence | denotes | 1)). |
| T73 | 2827-3016 | Sentence | denotes | Furthermore, as mentioned previously, the presence of the two capping loops in the binding domain is likely producing a stabilization effect over the interaction with the cellular receptor. |
| T74 | 3017-3131 | Sentence | denotes | Our models showed that these capping loops appear in both human-infecting viruses but are absent in the bat virus. |
| T75 | 3132-3301 | Sentence | denotes | The data showed here strongly suggest that these capping loops produce an increase in the electrostatic interactions between the spike protein and the cellular receptor. |
| T76 | 3302-3538 | Sentence | denotes | In SARS-CoV, the residues present in these capping loops showing direct interaction with the receptor are R426, S432, T433, Y436, P462, D463, S472, and N473 and in SARS-CoV-2 are V445, Y449, Y473, Q474, A475, E484, G485, F486, and N487. |
| T77 | 3539-3611 | Sentence | denotes | The counter-pairs located in the ACE2 receptor are shown in Table 1(Tab. |
| T78 | 3612-3615 | Sentence | denotes | 1). |
| T79 | 3616-3687 | Sentence | denotes | Altogether, the higher number of protein-protein contacts (Table 2(Tab. |
| T80 | 3688-3859 | Sentence | denotes | 2)) and the longer capping loops could explain the increase in binding affinities in SARS-CoV-2 (-15.7 Kcal/mol) in comparison with SARS-CoV (-14.1 Kcal/mol) (Table 3(Tab. |
| T81 | 3860-3864 | Sentence | denotes | 3)). |
| T82 | 3865-4046 | Sentence | denotes | Thus, these loops could play an important role together with the punctual mutations being an interesting clue to determine the host receptor specificity for the viral spike protein. |
