Abstact

We have achieved a novel co-crystal in which the dual functions of the protein and single-stranded DNA are maintained by introducing a charged peptide tag at the C-terminus of the protein. The functionalities allowed the co-crystals to be modified with high selectivity. Additionally, we have confirmed that energy transfer occurs between the two molecules modified within the co-crystal. Therefore, this co-crystal has the potential as a novel biomaterial applicable to biosensors.
