H7 Haemagglutinin
Overview
Comparing the structures of H3, H5 and H9 subtype haemagglutinins, we, deduced a structural basis for including all 15 influenza subtypes in four, clades. H3, H5 and H9 represent three of these clades; we now report the, structure of an H7 HA as a representative of the fourth clade. We confirm, the structure of the turn at the N-terminus of the conserved central, alpha-helix of HA2, and the combination of ionisable residues near the, "fusion peptide" as clade-specific features. We compare the structures of, three H1 HAs with H5 HA in the same clade, to refine our previous, classification and we confirm the division of the clades into two groups, of two. We also show the roles of carbohydrate side chains in the, esterase-fusion domain boundaries in the formation of clade-specific, structural markers.
