A model of the parallel three-stranded coiled coil peptides investigated in this study. The model is derived based on the X-ray structure of a related peptide CSL9C (CS = Coil Ser) (PDB ID: 3LJM).48 Peptide backbone is represented as gray cartoon, amino acid side chains that are modified yielding different derivatives of GRAND peptides (GrandL12AL16C, GrandL26AL30C, GrandL12AL16CL26AL30C, and GrandL26AE28QL30C) used in this study are shown as ball and stick representations. N→C terminus corresponds to top→bottom in this view parallel to the helical axis.
