Book Description
Iron–sulfur (FeS) centers are essential protein cofactors in all forms of life. They are involved in many key biological processes. In particular, Fe-S centers not only serve as enzyme cofactors in catalysis and electron transfer, they are also indispensable for the biosynthesis of complex metal-containing cofactors. Among these cofactors are the molybdenum (Moco) and tungsten (Wco) cofactors. Both Moco/Wco biosynthesis and Fe-S cluster assembly are highly conserved among all kingdoms of life. After formation, Fe-S clusters are transferred to carrier proteins, which insert them into recipient apo-proteins. Moco/Wco cofactors are composed of a tricyclic pterin compound, with the metal coordinated to its unique dithiolene group. Moco/Wco biosynthesis starts with an Fe-S cluster-dependent step involving radical/S-adenosylmethionine (SAM) chemistry. The current lack of knowledge of the connection of the assembly/biosynthesis of complex metal-containing cofactors is due to the sheer complexity of their synthesis with regard to both the (genetic) regulation and (chemical) metal center assembly. Studies on these metal-cofactors/cofactor-containing enzymes are important for understanding fundamental cellular processes. They will also provide a comprehensive view of the complex biosynthesis and the catalytic mechanism of metalloenzymes that underlie metal-related human diseases.

Book Description
International Series of Monographs in Analytical Chemistry, Volume 47: Analytical Chemistry of Molybdenum and Tungsten describes the chemical and instrumental methods of analysis of molybdenum and tungsten. This book is composed of 15 chapters that particularly consider detailed methods for determining these metals in typical samples and their alloys by both classical and modern techniques. The opening chapters discuss the history, occurrence, physico-chemical properties, and applications of molybdenum and tungsten. The succeeding chapters deal with the metals’ sampling, decomposition, separation, and qualitative detection. Considerable chapters are devoted to various chemical and instrumental methods for their analysis, including gravimetry, titrimetry, colorimetry, polarography, amperometry, coulometry, emission and atomic absorption spectroscopy, X-ray spectrophotometry, mass spectrometry, and radiochemical methods. The concluding chapter examines the determination of impurities and alloying elements. This book will prove useful to analytical and inorganic chemists, as well as analytical and inorganic chemistry students.
