Fig. 6: Group 3 mAb LN1F9 shares epitopes with human and macaca mAbs.

A–F Structural comparisons of mAbs targeting the GH of NiV and HeV. The mAb groups were defined based on the superimposition of the complexes, using GH as a reference. Receptor ephrin-B2 (PDB: 2VSM) is displayed as a cartoon and colored palegreen. Group 3 mAbs: HENV26 (PDB: 6VY5), m102.3 (PDB: 6CMG), 41-6 (PDB: 8K3C), 1E5 (PDB: 8K0D), and LN1F9 are shown as cartoons in green, teal, lightteal, smudge and green, respectively. Group 1 mAb S1E2 is in blue, group 2 mAb S2B10 is in yellow, group 4 mAbs LN3D3 and nAH1.3 (PDB: 7TXZ) are in red and salmon, group 5 mAbs HENV32 (PDB: 6VY4) and n425 (PDB: 8XPS) are in cyan and palecyan, and group 6 mAb hAH1.3 is in magenta. G Sequence alignment of GH from NiV and HeV, with structurally defined epitopes highlighted. The binding footprints of group 3 mAbs are colored green and the other groups are colored as in panel (A). The amino acids recognized by ephrin-B2 are marked with a black triangle below the sequence, and the common footprints recognized by ephrin-B2 and group 3 mAbs are indicated with red boxes.
