Solution structure of amyloid beta-peptide (25-35) in different media.

The design of molecules able to interact with the amyloid peptides either as inhibitors of fibril formation or as inhibitors of amyloid membrane pore formation represents one of the most relevant approaches in the development of anti-Alzheimer therapies. Abeta-(25-35), sequence GSNKGAIIGLM, is a highly toxic synthetic derivative of amyloid beta-peptides (Abeta-peptides), which forms fibrillary aggregates. Here, we report the NMR and CD investigation of Abeta-(25-35) in a membrane-mimicking environment and in isotropic mixtures of water and fluoro-alcohols to scan its conformational properties as a function of the medium. The analysis of the 3D structures in the mentioned conditions indicates a propensity of the peptide to behave as a typical transmembrane helix in the lipidic environment. In media characterized by different polarity, it loses the structural regularity at specific points of the sequence as a function of the environment. Furthermore, a comparison with the solution structure of full-length amyloid peptides suggests a role for the 25-27 kink region, which appears to be a general feature of all peptides under the solution conditions explored.

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time. Where a reference describes a PDB structure, the PDB code is shown on the right.
