SARS-CoV-2 spike protein, molecular model. The spike protein of SARS-CoV-2 is shown here as a ribbon structure covered with a semi-transparent surface. Helical regions are coloured purple, the sheet segments are coloured green, and the random coil is shown in grey. The spike is a protease enzyme embedded in the surface membrane of the virus. After binding to a receptor site on the host, a fusion process between the two partners creates a passage that allows viral RNA (ribonucleic acid) to enter the host cell. | |
