dc.description.abstract | Amyloid proteins are known to be the main cause of numerous degenerative and neurodegenerative diseases. In general, amyloids are misfolded from monomers and they tend to have beta-strand formations. These misfolded monomers are then transformed into oligomers, fibrils, and plaques. It is important to understand the forming mechanism of amyloids in order to prevent degenerative diseases to occur. A beta protein is a highly noticeable protein which causes Alzheimer's disease. It is reported that solvents affect the forming mechanism of A beta amyloids. In this research, A beta(1-42) was analyzed using an all-atom MD simulation with the consideration of effects induced by two disparate solvents: water and DMSO. As a result, two different conformation changes of A beta(1-4) were exhibited in each solvent. It was found that salt-bridge of Asp23 and Lys28 in A beta(1-4) was the key for amyloid folding based on the various analysis including hydrogen bond, electrostatic interaction energy and salt-bridge distance. Since this salt-bridge region plays a crucial role in initiating the misfolding of A beta(1-4), this research may shed a light for studies related in amyloid folding and misfolding.
