The results of a NATO Advanced Study Institute (ASI) entitled "Coordination Chemistry Environments in Iron-Containing Proteins and Enzymes - Including Smaller Molecules and Model Systems" are summarized in this book. The ASI was held in the Province of Alberta, Canada, from August 23 to September 4, 1981. The first half of the conference was held on the campus of the University of Alberta, Edmonton, and the second half at the Overlander Lodge, Hinton. Two other conferences had the greatest impact upon the planning for this ASI. One was a NATO ASI held in Tomar, Portugal in September of 1979, entitled "Metal Ions in Biology". Among the organizers for that conference were Allen Hill and Antonio Xavier; we are happy to acknowledge their beneficial influence on our subsequent conference. The other most influential conference was one organized by Ralph Wilkins and Dennis Darnell entitled "Methods for Determining Metal Ion Environments in Proteins" which was held in Las Cruces, New Mexico, U.S.A., January 10-12, 1979. The Las Cruces conference invited lectures were published as Volume 2 of "Advances in Inorganic Biochemistry", G. Eichhorn and L. Marzilli, editors.
The reduction of nitrate to nitrogen by metalloenzymes is a vital step in the nitrogen cycle. The importance of this pathway has inspired efforts to understand in greater depth the mechanisms involved. This book presents and discusses the latest information on multiple aspects of denitrification. Written by recognized specialists in the field, this book describes the bioinorganic aspects and the key enzymes involved in denitrification, including their structure, function and mechanisms. Active site modelling, novel methodologies for monitoring denitrification in vivo and biotechnological methods for water treatment are discussed. The book also focusses on the environmental implications of denitrification, such nitrate accumulation and the release of nitrous oxide into the atmosphere from excessive fertiliser use. An important topic in many biological, environmental and agricultural contexts, this book will aid teaching and help bioinorganic chemists and biotechnologists gain an up-to-date picture of the science behind the denitrification process.
There has been enormous progress in our understanding of molybdenum and tungsten enzymes and relevant inorganic complexes of molybdenum and tungsten over the past twenty years. This set of three books provides a timely and comprehensive overview of the field and documents the latest research. The first volume in the set focusses on the enzymes themselves, and discusses active sites and substrate channels of relevant proteins. The book begins with an introductory overview of the whole field. Chapters are contributed by world leaders and topics covered include pyranopterin cofactor biosynthesis and incorporation of the mature cofactor into apoprotein. Subsequent volumes cover the bioinorganic chemistry relevant to these enzymes and the full range of spectroscopic and theoretical methods that are used to investigate their physical and electronic structure and function. This text will be a valuable reference to workers both inside and outside the field, including graduate students and young investigators interested in developing new research programs in this area.
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 fie lds of high-resolution EPR, metalloenzymes, and metals in biology.
