Mock co-complexes of C05 IgG with each subtype were created by aligning the HA structure to antigen in the co-crystal structure of C05 (PDB ID 4fp8). Peptides C05 d1 and C05 truncated d4 were docked into the receptor-binding site of each HA and the buried surface area of the lowest energy model was calculated.
