The role of copper and protons in heme-copper oxidases: Kinetic study of an engineered heme-copper center in myoglobin

To probe the role of copper and protons in heme-copper oxidase (HCO), we have performed kinetic studies on an engineered heme-copper center in sperm whale myoglobin (Leu-29 → His/Phe-43 → His, called Cu(B)Mb) that closely mimics the heme-copper center in HCO. In the absence of metal ions, the engine...
