Toward this end, we investigated the mechanisms controlling beta-sheet curvature by studying the geometry of beta sheets in naturally occurring protein structures and folding simulations. The principles emerging from this analysis were used to design, de novo, a series of proteins with curved beta sheets topped with alpha helices. Nuclear magnetic resonance and crystal structures of the designs closely match the computational models, showing that beta-sheet curvature can be controlled with atomic-level accuracy. Our approach enables the design of proteins with cavities and provides a route to custom design ligand-binding and catalytic sites.
