Abstract excerpt
A 43-mer peptide derived from the coiled coil domain of the transmembrane glycoprotein, gp41, of human immunodeficiency virus type 1, was synthesized. Light scattering measurements suggested that the peptide molecules likely exist in the aqueous solution in trimeric form. Circular dichroism experiments showed a moderate helix population enhancement for the peptide in 80% methanol solution relative to helicity in...
