  • PubMed Abstract: 

    Protein crystals are formed via ordered arrangements of proteins, which assemble to form supramolecular structures. Here, we show a method for the assembly of supramolecular protein cages within a crystalline environment. The cages are stabilized by covalent cross-linking allowing their release via dissolution of the crystal. The high stability of the desiccated protein crystals allows cages to be constructed.
