Self-assembly of penta-selenopeptides into amyloid fibrils

Chem Commun (Camb). 2018 Oct 16;54(83):11697-11700. doi: 10.1039/c8cc06528d.

Abstract

Here, we report the synthesis of a penta-selenopeptide consisting of five benzyl protected selenocysteine residues. This selenopeptide was well characterized by both one- and two-dimensional (D) NMR spectroscopies. We find that the solution conformation is enriched with β-sheet structures, which have a propensity to self-assemble and form amyloid fibrils.
