Site-moiety maps of NAs. (A) Anchor locations of H1N1 and H5N1 NAs. (B) Anchor residues. (C) Moiety preferences of anchors. H1, V1, and H2 are located in the 150-cavity, while the sialic acid binding site contained five anchors. Green, gray, and red anchors present the hydrogen, van der Waals, and electrostatic anchors, respectively. H1N1 and H5N1 NAs are colored by slate and yellow, respectively.
