The potential of artificialmetalloenzymes has led to an increase in interest for the design of novel metal-binding sites in proteins. Metal-chelating unnatural amino acids offer an auspicious solution to engineer active metal sites in a defined way. Herein, we describe the introduction of four metal-chelating unnatural amino acids into HaloTag, an attractive scaffold for the assembly of functional

ET encounters jellyfish: Through the incorporation of the metal‐chelating aminoacid pyTyr into green fluorescent protein (GFP) from jellyfish, photoinduced electrontransfer (ET) from the GFP chromophore to a bound CuII ion was shown to occur within one nanosecond in a distance‐dependent manner. The crystal structure of GFP with pyTyr at a specific position shows the structural basis for the nanomolar
