Hemagglutinin Receptor Specificity and Structural Analyses of Respiratory Droplet-Transmissible H5N1 Viruses.
J.Virol., 88:768-773, 2014

PubMed Abstract: Two ferret-adapted H5N1 viruses capable of respiratory droplet transmission have been reported with mutations in the hemagglutinin receptor-binding site and stalk domains. Glycan microarray analysis reveals that both viruses exhibit a strong shift toward binding to "human-type" α2-6 sialosides but with notable differences in fine specificity. Crystal structure analysis further shows that the stalk mutation causes no obvious perturbation of the receptor-binding pocket, consistent with its impact on hemagglutinin stability without affecting receptor specificity.
