Figure 2. Overall structure of SARS-CoV-2 RBD bound to ACE2 (6M0J)12
ACE2 is shown in green. The SARS-CoV-2 RBD core is shown in cyan and RBM in red. Disulfide bonds in the SARS-CoV-2 RBD are shown as sticks and indicated by arrows. The N-terminal helix of ACE2 responsible for binding is labelled.
The structure of SARS-CoV-2 spike protein in prefusion state (flexibility analysis, 1-up open conformation) (PDB ID = 6ZP7) is shown in figure 3 to complete information. This structure was used as receptor for docking with ligands to consider interactions.
