Molecular dynamics simulation of the effects of single (S221P) and double (S221P and K216E) mutations in the hemagglutinin protein of influenza A H5N1 virus: a study on host receptor specificity.

Abstract excerpt

Avian influenza viruses of subtype H5N1 circulating in animals continue to pose threats to human health. The binding preference of the viral surface protein hemagglutinin (HA) to sialosaccharides of receptors is an important area for understanding mutations in the receptor binding site that could be the cause for avian-to-human transmission. In the present work, we studied the effect of two receptor binding site...
