Sub-processes in the hierarchical self-assembly ofβ-sheet peptides:β-sheet locking along the hydrogen bonding direction (the long axis growth), which is responsible for the elongation of assemblies, lateral stacking ofβ-sheets along the side chain direction for the width growth, and morphological transformation of assemblies with different widths. {H,S,P} is the local coordinate of the peptide, whereHis the hydrogen bonding direction,Sis the side chain direction, andPis the backbone direction from the N-terminus to the C-terminus.[30] |
