Crystal structure of Top7: A computationally designed protein with a novel fold
Overview
A major challenge of computational protein design is the creation of novel, proteins with arbitrarily chosen three-dimensional structures. Here, we, used a general computational strategy that iterates between sequence, design and structure prediction to design a 93-residue alpha/beta protein, called Top7 with a novel sequence and topology. Top7 was found, experimentally to be folded and extremely stable, and the x-ray crystal, structure of Top7 is similar (root mean square deviation equals 1.2, angstroms) to the design model. The ability to design a new protein fold, makes possible the exploration of the large regions of the protein, universe not yet observed in nature.
