Figure 4
Projection of the molecular packing on the c axis. Only the peptide backbones are drawn. The molecules are rotated helically. The rotation angles were calculated for least-squares planes composed of ten Cα atoms (Figs. S7 and S8 in the supporting information). Dotted lines (straight) show the approximate plane positions. The rotating angles formed by the planes are A⋯B = 104°, B⋯C = 139° and C⋯A = 117°. |
