Two modes of fusogenic action for influenza virus fusion peptide
Fig 4
(A) Distributions of local (0.5 nm × 0.5 nm bins in XY plane) instantaneous interbilayer distances in considered systems. (B) Sample geometries of lipid tail protrusion and N-P contact between lipids from the opposing membranes. (C-D) Correlation between local interbilayer distance and the frequency of N-P contacts (C) or lipid tails protrusions (D). (E) Residue-based mean minimum distance profiles between HAfp and opposing membrane heavy atoms. (F) The distribution of ϕ angle (see text for definition) for surface HAfp hairpin in single and double bilayer systems. Shadows (A, E) correspond to one standard deviation.
