Extended Data Fig. 3: The 3′-vRNA promoter end resting outside in FluPolH5N1.

The structure of the vRNA promoter in FluPolH5N1 complex is shown as cartoon (left) and stick (right) representations. Interacting residues in FluPolH5N1 stabilized the 3′-vRNA promoter end are shown as stick representation. For clarity, only polar interactions are shown as black dashed lines. Colors are shown as same as those in Fig. 1a.
