However, nearly all nanoparticles designed to date exhibit strict point group symmetry, with each subunit occupying an identical, symmetrically related environment. This limits the structural diversity that can be achieved and precludes anisotropic functionalization. Here, we describe a general computational strategy for designing multi-component bifaceted protein nanomaterials with two distinctly addressable sides. The method centers on docking pseudosymmetric heterooligomeric building blocks in architectures with dihedral symmetry and designing an asymmetric protein-protein interface between them. We used this approach to obtain an initial 30-subunit assembly with pseudo-D5 symmetry, and then generated an additional 15 variants in which we controllably altered the size and morphology of the bifaceted nanoparticles by designing extensions to one of the subunits. Functionalization of the two distinct faces of the nanoparticles with protein minibinders enabled specific colocalization of two populations of polystyrene microparticles coated with target protein receptors. The ability to accurately design anisotropic protein nanomaterials with precisely tunable structures and functions could be broadly useful in applications that require colocalizing two or more distinct target moieties. | |||||||||||||||

Batches of A, B, and C components or A, B, and D components were mixed, subsequently lysed and centrifuged to yield 2 distinct species of cyclic assemblies - (ABC)5 and (ABD)5. Following IMAC and SEC, (ABC)5 and (ABD)5 assemblies were mixed to form pseudo-D5 (ABC)5-(ABD)5 assembly pD5-14. |
