Functional Motions of Influenza Virus Hemagglutinin (HA)

Residue mean-square fluctuations driven by the first (global) mode HA trimer in HA. 

  • Each monomer has identical behavior

  • The residues at the recognition site occupy maxima in the HA1 curve.
  • Two lowermost minima are in close agreement with the residues pointed out by White et al. (1987) to form the hinge region of HA.
