Oxidative modification due to reactive oxygen species generated by Cu2+ bound to the amyloid-β peptide may be one of the sources of neurodegeneration observed in Alzheimer’s disease. Understanding the structure and function of the copper binding site can assist in the design of effective therapeutics. This paper highlights some of the most significant recent developments in computational modelling studies of the structure of the binding site and reaction mechanisms of reactive oxygen species generation.

Inheritance of the apolipoprotein E (apoE) ϵ4 allele is a risk factor for late-onset Alzheimer's disease (AD). Biochemically apoE is present in AD plaques and neurofibrillary tangles of the AD brain. There is a high avidity and specific binding of apoE and the amyloid β-peptide (Aβ). In addition to AD apoE is also present in many other cerebral and systemic amyloidoses, Down's syndrome and prion diseases but the pathophysiological basis for its presence is still unknown. In the present study we have compared the interaction of apoE with Aβ, the gelsolin-derived amyloid fragment AGel183-210 and the amyloidogenic prion fragments PrP109-122 and PrP109-141. We show that, similar to Aβ, also AGel and PrP fragments can form a complex with apoE, and that the interaction between apoE and the amyloidogenic protein fragments is mediated through the same binding site on apoE. We also show that apoE increases the thioflavin-T fluorescence of PrP and AGel and that apoE influences the content of β-sheet conformation of these amyloidogenic fragments. Our results indicate that amyloids and amyloidogenic prion fragments share a similar structural motif, which is recognized by apoE, possibly through a single binding site, and that this motif is also responsible for the amyloidogenicity of these fragments.
