A short segment of α-synuclein called NACore (residues 68–78) is responsible for the formation of amyloid aggregates responsible for cytotoxicity in Parkinson disease; here the nanocrystal structure of this invisible-to-optical-microscopy segment is determined using micro-electron diffraction, offering insight into its function and simultaneously demonstrating the first use of micro-electron diffraction to solve a previously unknown protein structure.
