Protein Structure from Scientific Research

A nanoparticle with dihedral symmetry ( D n ; in this example, n = 5) constructed from a single heterotrimeric building block requires two designed interfaces: an asymmetric interface around the n -fold symmetry axis and a symmetric interface along the dihedral two-fold axes. The assembly is anisotropic, but the two opposing faces are constructed from the same three subunits (labelled 1, 2 and 3) and are not independently addressable.
