Figure 4: Severe acute respiratory syndrome-coronavirus-2 has been shown to exhibit novel glycosylation sites in the spike glycoprotein of 2019-novel coronavirus, suggesting that the virus may utilize different glycosylation sites to interact with its receptors. Studies have demonstrated that severe acute respiratory syndrome-coronavirus-2 spike protein has higher af?nity to the angiotensin-converting enzyme 2 receptor as compared with severe acute respiratory syndrome[23] |
