Fig. 9.

(A) Molecular docking of BA-4 to Omicron spike protein (PDB: 7TF8). S1 subunit, S2 subunit, and BA-4 were shown as magenta ribbon, purple ribbon, orange sticks, respectively. Yellow dashes in the interaction plot indicating hydrogen bond. Red dashes in the interaction plot indicating hydrophobic interaction. (B) Molecular docking of BA-4 to spike protein (PDB: 6VXX). S1 subunit, S2 subunit, and BA-4 were shown as orange ribbon, blue ribbon, green sticks, respectively. Yellow dashes in the interaction plot indicating hydrogen bond.
