WebIn the Omicron HR1HR2 triple-mutant structure (Q954H, N969K, L981F) (Fig. 4F), the backbone of HR2 is slightly displaced, likely by the N969K mutation. The L981F mutation may also contribute to the small shift of the HR2 backbone, but its side-chain density is not well-resolved, perhaps since it is located furthest from the center of the scaffold.
