title: New cyclic peptide assemblies with hydrophobic cavities: the structural and thermodynamic basis of a new class of peptide nanotubes.
abstract: A new class of self-assembling peptides based on cyclic peptides made of alternating 3-aminocyclohexanecarboxylic acid (gamma-Acc) and alpha-amino acids is described. The studied cylindrical assemblies are models for a new class of self-assembling peptide nanotubes (SPN) that present the particular property of having the C2 methylene group pointing toward the lumen of the cavity, modifying the properties of the inner surface of the assembly.
