Understanding Protein Flexibility through Dimensionality Reduction
This work shows how to decrease the complexity of modeling flexibility in proteins by reducing the number of dimensions necessary to model important macromolecular motions such as the induced-fit process. Induced fit occurs during the binding of a protein to other proteins, nucleic acids, or small molecules (ligands) and is a critical part of protein function. It is now widely accepted that con...

P135: The Role of Amyloid Beta-Peptides and Tau Protein in Alzheimer\'s Disease
Alzheimer's desease is the most common age-related neurodegenerative disorder, and cognitive problems such as defects in learning and memory are of its symptoms. Among the factors involved in the pathogenesis of the disease are biochemical disorders in protein production, oxidative stress, decreased acetylcholine secretion and inflammation of the brain tissue. Extra-neuronal accumulation ...
متن کاملRole of water in protein aggregation and amyloid polymorphism.
A variety of neurodegenerative diseases are associated with amyloid plaques, which begin as soluble protein oligomers but develop into amyloid fibrils. Our incomplete understanding of this process underscores the need to decipher the principles governing protein aggregation. Mechanisms of in vivo amyloid formation involve a number of coconspirators and complex interactions with membranes. Never...
متن کاملDesigned Glycopeptidomimetics Disrupt Protein-Protein Interactions Mediating Amyloid β-Peptide Aggregation and Restore Neuroblastoma Cell Viability.
How anti-Alzheimer's drug candidates that reduce amyloid 1-42 peptide fibrillization interact with the most neurotoxic species is far from being understood. We report herein the capacity of sugar-based peptidomimetics to inhibit both Aβ1-42 early oligomerization and fibrillization. A wide range of bio- and physicochemical techniques, such as a new capillary electrophoresis method, nuclear magne...
