Figure 1. Clusters of closely-linked residues for H3N2 hemagglutinin.

Figure 1

Clusters identified by hierarchical clustering on sequence mutual information are visualized using crystallographic data. Red lines connect α-carbons within each cluster; sialic acid residues of the ligand are visualized via orange spheres.
