Abstract. Amyloid protein aggregation characterizes many neurodegenerative disorders, including Alzheimer’s, Parkinson’s, and Creutz- feldt-Jakob disease. Evidence suggests that amyloid aggregates may share similar aggregation pathways, implying simulation of full-length amyloid proteins is not necessary for understanding amyloid formation.

The kinetics and thermodynamics of protein folding is investigated using low friction Langevin simulation of minimal continuum mode of proteins. We show that the model protein has two characteristic temperatures: (a) T θ , at which the chain undergoes a collapse transition from an extended conformation; (b) T f (< T θ ), at which a finite size first‐order transition to the folded state takes place.
