We investigate the molecular mechanism of monomer addition to a growing amyloid fibril composed of the main amyloidogenic region from the insulin peptide hormone, the LVEALYL heptapeptide. Applying transition path sampling in combination with reaction coordinate analysis reveals that the transition from a docked peptide to a locked, fully incorporated peptide can occur in two ways. Both routes involve the formation of backbone hydrogen bonds between the three central amino acids of the… CONTINUE READING
