The Structural Dynamics of the Flavivirus Fusion Peptide–Membrane Interaction
The secondary structure patterns of the fusion peptides FLAG (A) and FLAH (B), at 35°C and secondary structure patterns of the FP FLAG (C) and FLAH (D) at 85°C in solution. (E and F) The MD simulation of FLAG (E) and FLAH (F) in water at 35°C (red line) and at 85°C (black line). (G and H) The minimal distance between FLAG (G) or FLAH (H) Trp101 and Phe108 residues at 35°C (red line) and at 85°C (black line). (I and J) The circular dichroism spectra of the FLAG (I) and FLAH (J) fusion peptides in solution at 25°C (solid line), at 85°C (dashed line), and the return to 25°C (dotted line). The experiments were performed at room temperature at pH 5.5.
