PubMed Abstract:
Metal-binding peptides are versatile building blocks in supramolecular chemistry. We recently reported a class of crystalline materials formed through a combination of coiled-coil peptide self-association and metal coordination. Here, we probe the serendipitously discovered metal binding motif that drives the assembly and apply these insights to exert rational control over structure and morphology in the materials.
