SARS CoV2 Fusion (IMAGE) Biophysical Society Caption The SARS-CoV-2 virus inserts itself into the membrane of a host human cell using a small part of its spike protein (yellow), called a fusion peptide. Computer simulations revealed the parts of peptide that are the most important for sticking to and inserting into the cell membrane. This illustration shows the fusion peptide (in blue) as it approaches, sticks to, and inserts into the membrane (brown, orange and gold). Credit Image courtesy of Defne Gorgun.
