Schematic representation of the structure and alignment of the model conjugates with a conformationally flexible (top) and rigidified (bottom) DAET linker. β/α-Model in lipid bilayers in the fluid (a) and gel phase (b). α/α-Model in lipid bilayers in the fluid (c) and gel phase (d). Conjugates are shown with space-filling for the DAET linkers (flexible – white, rigid - gray); peptide fragments are without hydrogens as stick-models with the secondary structures of the backbones highlighted as blue β-strands and red α-helices. Each observed situation is illustrated by a molecular model and a corresponding schematic summary; flexible DAET – white; rigid DAET – gray. All molecules are drawn to scale, but the depth of insertion is not known. The distortion of one α-helix in the symmetric model (d, bottom) is indicated by the purple color.
