Structures of SARS-Cov-2 receptor-binding domain (RBD) in complex with neutralizing antibodies and angiotensin-converting enzyme 2 (ACE2). (A) The complex structure of RBD with H11-D4 nanobody (PDB ID: 6YZ5). (B) The complex structure of RBD with P2B-2F6 Fab (PDB ID: 7BWJ). (C) The complex structure of RBD with SR4 sybody (PDB ID: 7C8V). (D) The complex structure of RBD with MR17 sybody (PDB ID: 7C8W). (E) The complex structure of RBD with ACE2 (PDB ID: 6M0J). (F) The complex structure of RBD with the VH1-2-15 nanobody (PDB ID: 7L5B). In all panels, the protein structures are shown in ribbons and colored in cyan (RBD) and green (antibodies) with the interactive residues (side chains) presented in sticks (magenta).
