N2 - ABSTRACT Developing novel building blocks with predictable side-chain orientations and minimal intramolecular interactions is essential for peptide-based self-assembling materials. Traditional structures like α-helices and β-sheets rely on such interactions for stability, limiting control over exposed interacting moieties. Here, we reported a novel, frame-like peptide scaffold that maintains exceptional stability without intramolecular interactions. This structure exposes its backbone and orients side chains for hierarchical self-assembly into micron-scale cubes. By introducing mutations at specific sites, we controlled packing orientations, offering new options for tunable self-assembly. Our scaffold provides a versatile platform for designing advanced peptide materials, with applications in nanotechnology and biomaterials.
