Inhibition by small-molecule ligands of formation of amyloid fibrils of an immunoglobulin light chain variable domain.

abstract：:β-Propellers arise through the amplification of a supersecondary structure element called a blade. This process produces toroids of between four and twelve repeats, which are almost always arranged sequentially in a single polypeptide chain. We found that new propellers evolve continuously by amplification from single...
