A metal-ion chelating amino acid, (8-hydroxyquinolin-3-yl)alanine, was genetically encoded inE. coliby an amber nonsense codon and corresponding orthogonal tRNA/aminoacyl-tRNA synthetase pair. The amino acid was incorporated into TM0665 protein, and the mutant protein was cocrystallized with Zn2+to determine the structure by SAD phasing. The structure showed a high occupancy of the heavy metal bound to the HQ-Ala residue, and the heavy metal provided excellent phasing power to determine the structure. This method also facilitates the de novo design of metalloproteins with novel structures and functions, including fluorescent sensors.
