Metalloproteins comprise approximately 30% of all known proteins and are involved in a variety of  biologically important processes, including oxygen trans- port, biosynthesis, electron transfer,  biodegradation, drug metabolism, proteolysis and hydrolysis of amides and esters, environmental  sulfur and nitrogen cycles, and disease mechanisms. EPR spectroscopy has an important role in not  only the geo- metric structural characterization of the redox cofactors in metalloproteins but also  their electronic structure, as this is crucial for their reactivity.
