The human immunodeficiency virus type-1 (HIV-1) fusion peptide (FP) functions as a non-constitutive membrane anchor that translocates into membranes during envelope glycoprotein-induced fusion. Here, by means of infrared spectroscopy (IR) and of various bilayer-perturbation assays, we describe the peptide conformations that are accessible to its membrane-bound state and the transitions occurring between them. The peptide underwent a conformational transition from a predominantly alpha-helical… CONTINUE READING
