Knowles, TP and Fitzpatrick, AW and Meehan, S and Mott, HR and Vendruscolo, M and Dobson, CM and Welland, ME (2007) Role of intermolecular forces in defining material properties of protein nanofibrils. Science, 318. pp. 1900-1903.Full text not available from this repository.
Protein molecules have the ability to form a rich variety of natural and artificial structures and materials. We show that amyloid fibrils, ordered supramolecular nanostructures that are self-assembled from a wide range of polypeptide molecules, have rigidities varying over four orders of magnitude, and constitute a class of high-performance biomaterials. We elucidate the molecular origin of fibril material properties and show that the major contribution to their rigidity stems from a generic interbackbone hydrogen-bonding network that is modulated by variable side-chain interactions.
