Methods for designing high-affinity interactions that adopt a predetermined binding mode have proved elusive, suggesting the need for new strategies that simplify the design process. A solvent-exposed backbone on a beta-strand is thought of as "sticky" and beta-strand pairing stabilizes many naturally occurring protein complexes. Here, we computationally redesign a monomeric protein to form a symmetric homodimer by pairing exposed beta-strands to form an intermolecular beta-sheet. A crystal structure of the designed complex closely matches the computational model (rmsd = 1.0 A). This work demonstrates that beta-strand pairing can be used to computationally design new interactions with high accuracy.
