Fusion Peptide Insertion Configuration Determines the Mechanism of Membrane Curvature Induction in Human Parainfluenza Virus Type 3

Viral entry requires remodeling the host membrane with a short fusion peptide (FP) that anchors and deforms the target lipid bilayer. However, the contribution of the FP throughout the full fusion pathway remains unknown. Here, all-atom molecular dynamics simulations define the membrane- deformation mechanisms associated with two distinct insertion configurations of membrane-bound human…
