In recent years, protein crystals receive much attention in the filed of nanobiomaterial sciences because they consist of highly ordered protein assemblies with unique nano reaction environments. Therefore, protein crystals have been utilized as nanosized porous materials for application in separation processes, heterogeneous catalysis, drug delivery, and so on. These crystals are able to capture and deposit metal ions and metal complexes within solvent channels because the amino acid side chains responsible for coordinating the metal ions are periodically aligned on the surface of solvent channels of the crystal lattices. Here, we elucidate accumulation process of metals by X-ray crystallographic analysis of protein crystals containing metal complexes or ions and apply to catalytic reactions and preparation of magnetic materials.
