TL;DR: The crystal structure of the C-terminal domain of SARS-CoV-2 (SARS- coV- 2-CTD) spike (S) protein in complex with human ACE2 (hACE2) is presented, which reveals a hACE2-binding mode similar overall to that observed for SARS -CoV.

TL;DR: High-resolution structures of the trimeric MERS- coV and SARS-CoV S proteins in its pre-fusion conformation are presented by single particle cryo-electron microscopy, demonstrating an inherently flexible RBD readily recognized by the receptor.

TL;DR: The crystal structure of the receptor binding domain of the MERS-CoV spike protein, both free and bound to the receptor, was presented in this article, which revealed a core subdomain homologous to that of the SARS-coV spike proteins, and a unique strand-dominated external receptor binding motif that recognizes blades IV and V of the CD26 β-propeller.

TL;DR: It is shown that a recombinant vaccine that comprises residues 319–545 of the RBD of the spike protein induces a potent functional antibody response in immunized mice, rabbits and non-human primates as early as 7 or 14 days after the injection of a single vaccine dose.

TL;DR: The progress made in the past decade in understanding the cross-species transmission of SARS- coV and MERS-CoV is summarized by focusing on the features of the S protein, its receptor-binding characteristics, and the cleavage process involved in priming.
