Answer:
Protein that is made up of 1,160 to 1,400 amino acids.
Step-by-step explanation:
The Spike protein is a type of protein that is made up of 1,160 to 1,400 amino acids. Different viruses have different amount of amino acids in their spike protein depending upon the type of virus. This spike protein is highly glycosylated and large type I transmembrane fusion protein. Spike protein is a glycoprotein that spreads from the envelope of some viruses which facilitates the virion in entering into a host cell.
