Can molecular dynamics simulations assist in design of specific inhibitors and imaging agents of amyloid aggregation? Structure, stability and free energy predictions for amyloid oligomers of VQIVYK, MVGGVV and LYQLEN.

Abstract excerpt

The aggregation modes of hexapeptide fragments of Tau, Insulin and Aβ peptide (VQIVYK, MVGGVV and LYQLEN) were found from their microcrystalline structures that had been recently resolved by X-ray analysis. The atomic structures reveal a dry self-complementary interface between the neighboring β-sheet layers, termed "steric zipper". In this study we perform several all-atom molecular dynamics simulations with...
