This model was prepared at the direction of Dr. 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 structure represents a complete Spike protein, and is a mixture of experimental and computer modeled data.
“Glycoprotein” means that it is mostly made of protein with attached sugars (but the sugars are not included on this model). The Spike glycoprotein projects from the outer surface of the SARS-CoV-2 virus and is the basis for COVID-19 vaccines.
