Ramachandran plots and typical structures. A) A preformed linear hexamer consisting of parallel β‐strands aligning at the surface through N‐terminal adsorption of the peptides. B) A preformed steric zipper hexamer (consisting of two β‐sheets with three parallel peptide strands within each sheet and antiparallel orientation of the two sheets towards each other) assembles on top of the (preassembled) peptide halo in the second adsorption layer. C) A peptide monomer adsorbed on the surface (left) and the corresponding Ramachandran plot of ASN6 during the 100 ns trajectory (right). The Ramachandran plot is highly occupied at very low phi angles and psi angles around 0°. This unusual pattern was observed for all amino acids that are highlighted in purple (C, D right). D) A preformed steric zipper dodecamer and the corresponding Ramachandran plot of the highlighted amino acids (purple) at its growing end, here exemplified using GLN5 (right) during the 100 ns trajectory.
