The RATG13 Bat Coronavirus Receptor Binding Domain (blue) is the most closely related known coronavirus to SARS-CoV-2. Each residue that creates a Hydrogen bond has been revealed to visualize both the intramolecular dynamics of protein structure as well as the intermolecular bonds that SARS-CoV-1 creates to bind ACE2 Receptors. This 3D-printed protein model was designed for scientists to study the different bonds formed by these residues.
