SARS-CoV-2 Spike protein, Smithsonian Futures Exhibit
SARS-CoV-2 Spike glycoprotein model displayed in the Smithsonian Institution Futures exhibit. The Spike glycoprotein projects from the outer surface of the SARS-CoV-2 virus and is the basis for COVID-19 vaccines. “Glycoprotein” means that it is mostly made of protein with attached sugars (but the sugars are not included on this model). This structure represents a complete Spike protein, and is a mixture of experimental and computer modeled data.
This structure is made up of 3 identical protein chains, two of them are shown here as red and blue molecular surfaces and the third is shown as a ribbon that indicates the path that the protein backbone takes under the surface with rainbow coloring varying from the start to the end of the protein chain.
This model was prepared at the direction of Dr. Barney Graham, the former Deputy Director of the Vaccine Research Center of the National Institute of Allergy and Infectious Diseases.See this entry
