Fusion of phospholipid vesicles induced by an amphiphilic model peptide: close correlation between fusogenicity and hydrophobicity of the peptide in an alpha-helix.

Abstract

A model peptide with 51 amino acid residues consisting of tandem repeats of a Lys-Lys-Leu-Leu sequence and a turn sequence of Asn-Pro-Gly at the center of the molecule has a random conformation at neutral pH but adopts an amphiphilic alpha-helical form in the presence of various salts or nucleotides [Goto, Y., & Aimoto, S. (1991) J. Mol. Biol. 218, 387-396… (More)
