| + | The assembly of the beta-amyloid peptide, Abeta, into soluble oligomers is associated with neurodegeneration in Alzheimer's disease. The Abeta oligomers are thought to be composed of beta-hairpins. Here, the effect of shifting the residue pairing of the beta-hairpins on the structures of the oligomers that form is explored through X-ray crystallography. Three residue pairings were investigated using constrained macrocyclic beta-hairpins in which Abeta30-36 is juxtaposed with Abeta17-23, Abeta16-22, and Abeta15-21. The Abeta16-22-Abeta30-36 pairing forms a compact ball-shaped dodecamer composed of fused triangular trimers. This dodecamer may help explain the structures of the trimers and dodecamers formed by full-length Abeta. | ||
