Fig 4. Interactions between the SARS-CoV-2 RBD and CDR loops.

Fig 4

(A–C) Detailed analysis of the interfaces of SARS-CoV-2 RBD with HCDR and LCDR for (A) PR1077, (B) PR953, and (C) PR961. For clarity, only the key residues are labeled: red, oxygen atoms; blue, nitrogen atoms; yellow dash lines, hydrogen bond interactions. The residues are shown in sticks with identical colors to Fig 3; water molecules are displayed as red spheres. CDR, complementary-determining region; HCDR, heavy chain complementarity-determining region; LCDR, light chain complementary-determining region; RBD, receptor-binding domain; SARS-CoV-2, Severe Acute Respiratory Syndrome Coronavirus 2.
