We previously devised a strategy (Metal-Directed Protein Self-Assembly, MDPSA) that utilizes the simultaneous stability, lability and directionality of metal-ligand bonds to drive protein-protein interactions. Here we show that both the structural and the functional scope of MDPSA can be broadened by non-natural metal chelating ligands incorporated onto protein surfaces. A cytochrome cb562 variant, MBP-Phen1, which features a covalently attached phenanthroline (Phen) group on its surface, self-assembles into an unusual triangular architecture (Ni3:MBP-Phen13) upon binding Ni, owing to specific Phenprotein interactions. The crystal structure of Ni3:MBP-Phen13 reveals that the Phen group is buried in a small pocket on the protein surface, which results in an unsaturated Ni coordination environment.
