Homology modeling study toward identifying structural properties in the HA2 B-loop that would influence the HA1 receptor-binding site
Amino acid residue 882 in the B-loop is strain-conserved. Substituting amino acid residue 882 affects the receptor-binding site. Amino acid orientation at residue 882 also affects the receptor-binding site.
