Patent ID: 7989591

Claim:
A protein lattice having a regular structure with a repeating unit repeating in three dimensions, the repeating unit comprising protein protomers, wherein each protein protomer comprises at least a first monomer and a second monomer genetically fused together or chemically fused together by a covalent linkage, the monomers each being a monomer of an oligomer assembly into which the monomers are assembled for assembly of the protomers into the lattice, and wherein said first monomer is a monomer of a first oligomer assembly which has at least three rotational symmetry axes; and wherein said second monomer is a monomer of a second oligomer assembly, said second oligomer assembly having a rotational symmetry axis of the same order as one of the at least three rotational symmetry axes of the first oligomer assembly and being aligned with the one of the at least three rotational symmetry axes of the first oligomer assembly when said protomers self-assemble into the lattice.
