Sinclair, J.C. et al. Nat. Nanotechnol. 6, 558–562 (2011).

Although nanostructures of ever-increasing complexity are being built using principles of DNA 'origami', protein molecules have been underexploited. Sinclair et al. now describe a general strategy to design ordered protein materials. One- and two-dimensional protein lattices can be constructed by the fusion of peptide chains derived from multisubunit protein complexes with matching rotational symmetry.
