abstract = {The aggregation of the Aβ plays a fundamental role in the
pathology of AD. Recently, N-terminally modified Aβ
species, pE-Aβ, have been described as major constituents
of Aβ deposits in the brains of AD patients. pE-Aβ has an
increased aggregation propensity and shows increased
toxicity compared with Aβ1-40 and Aβ1-42. In the present
work, high-resolution NMR spectroscopy was performed to
study pE-Aβ3-40 in aqueous TFE-containing solution.
Two-dimensional TOCSY and NOESY experiments were performed.
On the basis of NOE and chemical shift data, pE-Aβ3-40 was
shown to contain two helical regions formed by residues
14-22 and 30-36. This is similar as previously described for
Aβ1-40. However, the secondary chemical shift data indicate
decreased helical propensity in pE-Aβ3-40 when compared
with Aβ1-40 under exactly the same conditions. This is in
agreement with the observation that pE-Aβ3-40 shows a
drastically increased tendency to form β-sheet-rich
structures under more physiologic conditions. Structural
studies of pE-Aβ are crucial for better understanding the
structural basis of amyloid fibril formation in the brain
during development of AD, especially because an increasing
number of reports indicate a decisive role of pE-Aβ for the
pathogenesis of AD. Copyright © 2012 European Peptide
