Sequence-dependent backbone dynamics of a viral fusogen transmembrane helix.

Abstract excerpt

The transmembrane domains of membrane fusogenic proteins are known to contribute to lipid bilayer mixing as indicated by mutational studies and functional reconstitution of peptide mimics. Here, we demonstrate that mutations of a GxxxG motif or of Ile residues, that were previously shown to compromise the fusogenicity of the Vesicular Stomatitis virus G-protein transmembrane helix, reduce its backbone dynamics as...
