Abstract: The invention relates to the atomistic functional understanding of the M2 protein from the influenza A virus. This acid-activated selective proton channel has been the subject of numerous conductance, structural, and computational studies.

The structure of the M2 conductance domain in a lipid bilayer is disclosed and displays the defining features of the native protein that have not been attainable from structures solubilized by detergents. A detailed mechanism for acid activation and proton conductance, involving a strong hydrogen bond between two adjacent histidines and specific interactions with the tryptophan gate, is provided and elucidates many observations on the M2 proton conductance.
