thumb|260 px| Pincer-1: A designed heme-binding peptide adopting an all-beta secondary structure. ABOVE: Topological representation of Pincer-1 showing the secondary structure and designed interacting residues. BELOW: All-atom 3-dimensional model of Pincer-1. This model was partially confirmed using NMR.
