Protein detail:
| Protein name | spike glycoprotein |
| Uniprot protein ID | P59594 |
| Protein length | 1255 amino acids |
| Protein description | The spike protein of SARS coronaviruses is a protein composed of three polypeptide chains and it contains two domains, S1 and S2. The S1 domain binds the host cell receptors, while the S2 domain is responsible for the fusion of the virus with the host cell membrane. Between S1 and S2, there is a hinge region which is targeted by the host cell proteases. |
