Abstract

A protoheme derivative with covalently-bound tris(2,2′-bipyridine) ruthenium (II) [Ru(bpy)3]2+ was successfully incorporated into apo-myoglobin. In the reconstituted myoglobin emission of *[Ru(bpy)3]2+ was quenched intramolecularly, the efficiency being greater by more than 30-fold than that of the corresponding intermolecular process.
