Book Description
Biological enzymes utilize various copper-based active sites to activate dioxygen creating a variety of copper-dioxygen assemblies. These assemblies carry out highly selective and difficult oxidative transformations vital to biological life. Insight into how Nature has optimized these active sites can be gleaned by studying synthetic structural mimics and has potential to be of great benefit to the industrial design of catalysts. While the resting structures of many of these active sites are known, the nature of the active oxidants are often less well-defined. In this thesis, efforts towards the cryogenic synthesis and spectroscopic characterization of copper(III)-containing oxidants, formed directly via dioxygen activation of biomimetic copper precursors, will be discussed. This work demonstrates both the kinetic and thermodynamic accessibility of the copper(III) oxidation state under biological ligation, which challenges existing assumptions in the literature through the identification of reactive intermediates.

Book Description
Molecular self-assembly is a widespread phenomenon in both chemistry and biochemistry. Yet it was not until the rise of supramolecular chemistry that attention has increasingly been given to the designed self-assembly of a variety of synthetic molecules and ions. To a large extent, success in this area has reflected knowledge gained from nature. However, an increased awareness of the latent steric and electronic information implanted in individual molecular components has also contributed to this success. Whilst not yet approaching the sophistication of biological assemblies, synthetic systems of increasing subtlety and considerable aesthetic appeal have been created. Self-Assembly in Supramolecular Systems surveys highlights of the progress made in the creation of discrete synthetic assemblies and provides a foundation for new workers in the area, as well as background reading for experienced supramolecular chemists.

Book Description
This monograph consists of the proceedings of the Fifth International Symposium on the Activation of Dioxygen and Homogeneous Catalytic Oxidation, held in College Station, Texas, March 14-19, 1993. It contains an introductory chapter authored by Professors D. H. R. Barton and D. T. Sawyer, and twenty-nine chapters describing presentations by the plenary lecturers and invited speakers. One of the invited speakers, who could not submit a manuscript for reasons beyond his control, is represented by an abstract of his lecture. Also included are abstracts of forty-seven posters contributed by participants in the symposium. Readers who may wish to know more about the subjects presented in abstract form are invited to communicate directly with the authors of the abstracts. This is the fifth international symposium that has been held on this subject. The first was hosted by the CNRS, May 21-29, 1979, in Bendor, France (on the Island of Bandol). The second meeting was organized as a NATO workshop in Padova, Italy, June 24-27, 1984. This was followed by a meeting in Tsukuba, Japan, July 12-16, 1987. The fourth symposium was held at Balatonfured, Hungary, September 10-14, 1990. The sixth meeting is scheduled to take place in Delft, The Netherlands (late Spring, 1996); the organizer and host will be Professor R. A. Sheldon.

Book Description
Summarizes the essential biosynthetic pathways for assembly of metal cofactor sites in functional metalloproteins Metalloprotein Active Site Assembly focuses on the processes that have evolved to orchestrate the assembly of metal cofactor sites in functional metalloproteins. It goes beyond the simple incorporation of single metal ions in a protein framework, and includes metal cluster assembly, metal-cofactor biosynthesis and insertion, and metal-based post-translational modifications of the protein environments that are necessary for function. Several examples of each of these areas have now been identified and studied; the current volume provides the current state-of-the-art understanding of the processes involved. An excellent companion to the earlier book in this series Metals in Cells—which discussed both the positive and negative effects of cellular interactions with metals—this comprehensive book provides a diverse sampling of what is known about metalloprotein active site assembly processes. It covers all major biological transition metal components (Mn, Fe, Co, Ni, Mo), as well as the other inorganic components, metal-binding organic cofactors (e.g., heme, siroheme, cobalamin, molybdopterin), and post-translationally modified metal binding sites that make up the patchwork of evolved biological catalytic sites. The book compares and contrasts the biosynthetic assembly of active sites involving all biological metals. This has never been done before since it is a relatively new, fast-developing area of research. Metalloprotein Active Site Assembly is an ideal text for practitioners of inorganic biochemistry who are studying the biosynthetic pathways and gene clusters involved in active site assembly, and for inorganic chemists who want to apply the concepts learned to potential synthetic pathways to active site mimics.
