Critical roles of N165, N234, and N343 glycans in the transition between RBD open and closed conformations. (A) The open-state RBD (6VSB_A, pale yellow) is above N165 (red) and N234 (cyan) glycans on the neighboring NTD. (B) The closed-state RBD (6VSB_B) is between N165 and N234 glycans. (C) Frequency of contacts between the RBD and two glycans (N165 and N234). (D) N343 (magenta) glycan on the open-state RBD (6VSB_A) is free. (E) N343 glycan on the closed-state RBD (6VSB_C) interacts with the neighboring closed-state RBD (6VSB_C). (F) Frequency of contacts between N343 glycan and the neighboring RBD.
