Here, we tested the binding between equine angiotensin converting enzyme 2 (eqACE2) and the receptor binding domains (RBDs) of SARS-CoV, SARS-CoV-2 prototype (PT) and variant of concerns (VOCs), as well as their close relatives bat-origin coronavirus (CoV) RaTG13 and pangolin-origin CoVs GX/P2V/2017 and GD/1/2019. We also determined the crystal structures of eqACE2/RaTG13-RBD, eqACE2/SARS-CoV-2 PT-RBD and eqACE2/Omicron BA.1-RBD. We identified S494 of SARS-COV-2 PT-RBD as an important residue in the eqACE2/SARS-COV-2 PT-RBD interaction and found that N501Y, the commonly recognized enhancing mutation, attenuated the binding affinity with eqACE2. Our work demonstrates that horses are potential targets for SARS-CoV-2 and highlights the importance of continuous surveillance on SARS-CoV-2 and related CoVs to prevent spillover events.
