SARS-CoV-2 Receptor Binding Domain (light-green) and its Binding Motif (dark green) are responsible for binding ACE2 receptors. Residues of the Delta Plus mutation are exposed and their carbon atoms colored cyan, oxygen colored red, and nitrogen colored blue (K417N, T478K, L452R). This 3D-printed protein model was designed for scientists to study impact of Omicron mutations.
