Fig. 6.10 Schematic representation of the protein modification approaches applied to four peroxidases (Horseradish, chloroperoxidase, cytochrome c, and C. cinereous peroxidase) and proteins with pseudoperoxidase activity (cytochrome P450, myoglobin, and cytochrome c). The dashed arrows link each specific protein modification with the properties improved...
