Abstract

The SARS-CoV-2 virus has been known to gain entry into the host cell through the spike protein that binds to the host ACE2 cell surface protein. However, the role of the putative sugar-binding sites in the spike protein has remained unclear. We provide a comprehensive in silico outlook into the infection initiation wherein the virus first recognizes the sialosides on the cell via its S1A domain of the spike protein as it surfs over the cell surface. This facilitates the subsequent interaction with the cellular glycosaminoglycans through the S1B domain of the spike protein as it binds to the ACE2 receptor. The unique coadaptation to recognize both the host protein and the cell-surface carbohydrate receptors provides an additional coupling mechanism for efficient viral attachment and infection. © 2021 American Chemical Society.
