This book covers the latest developments in metalloenzymes, including characterizing metal bridging in proteins and peptides, copper(II) complexes of marine peptides, high-spin Co(II) in model and metalloprotein systems to enzymes such as the molybdenum-containing enzymes, CW and pulse EPR of cytochrome P450 enzymes and the radical S-adenosylmethionine FeS family. In the previous two related volumes in the Biological Magnetic Resonance series, High-Resolution EPR: Applications to Metalloenzymes and Metals in Medicine and Metals in Biology:Applications of High-Resolution EPR to Metalloenzymes, topics covered included high-resolution EPR methods, iron proteins, nickel and copper enzymes, metals in medicine, iron-sulfur cluster-containing proteins, and molybdenum enzymes. In this volume, new developments in these areas are covered in detail and new areas that have emerged are also detailed. This is an ideal book for graduate students and researchers working in the fields of high-resolution EPR, metalloenzymes, and metals in biology.
