Self-Assembly Of Amyloid Aggregates Simulated With Molecular Dynamics, Workalemahu Mikre Berhanu

Electronic Theses and Dissertations

Amyloids are highly ordered cross-β sheet aggregates that are associated with many diseases such as Alzheimer‟s, type II diabetes and prion diseases. Recently a progress has been made in structure elucidation, environmental effects and thermodynamic properties of amyloid aggregates. However, detailed understanding of how mutation, packing polymorphism and small organic molecules influence amyloid structure and dynamics is still lacking. Atomistic modeling of these phenomena with molecular dynamics (MD) simulations holds a great promise to bridge this gap. This Thesis describes the results of MD simulations, which provide insight into the effects of mutation, packing polymorphism and molecular inhibitors on amyloid …
