## Abstract We introduce a de novo designed peptide model system that enables the systematic study of 1) the role of a membrane environment in coiled‐coil peptide folding, 2) the impact of different domains of an α‐helical coiled‐coil heptad repeat on the interaction with membranes, and 3) the dyna
Reduced lattice models of the three de novo designed helical proteins ␣ 2 , ␣ 2 C, and ␣ 2 D were studied. Low temperature stable folds were obtained for all three proteins. In all cases, the lowest energy folds were four-helix bundles. The folding pathway is qualitatively the same for all proteins
