When the protein sequence of the SARS-CoV-2 receptor binding site was analyzed, an interesting result was found. While SARS-CoV-2 is overall more similar to bat coronaviruses, the receptor binding site was more similar to SARS-CoV.

Both SARS-CoV-2 and SARS-CoV use the same host cell receptor. It also found that, for both viruses, the viral proteins used for host cell entry bind to the receptor with the same tightness (affinity).

Knowledge is power.
