Biological chemistry is a major frontier of inorganic chemistry. Three special volumes devoted to Metal Sites in Proteins and Models address the questions: how unusual ("entatic") are metal sites in metalloproteins and metalloenzymes compared to those in small coordination complexes? and if they are special, how do polypeptide chains and co-factors control this? The chapters deal with iron, with metal centres acting as Lewis acids, metals in phosphate enzymes, with vanadium, and with the wide variety of transition metal ions which act as redox centres. They illustrate in particular how the combined armoury of genetics and structure determination at the molecular level are providing unprecedented new tools for molecular engineering.

This book describes in 13 chapters mechanisms of P450 used to monooxygenate substrates via the NAD(P)H/O2 pathway using its peroxidase and peroxygenase functions. P450 also utilizes peroxides, peracids, periodate and iodosobenzene to oxygenate substrates via the shunt pathway. Also described are mechanisms used in the oxidation of pharmaceuticals by CYP3A4; acyl- carbon cleavage by CYP17A1, CYP19A1 and CYP51A1; metabolism of tetrabromodiphenyl ethers and bile acids by CYP2B6 and CYP3A4; metabolism of ω-6 and ω-3 polyunsaturated fatty acids; H2O2-mediated peroxygenation of substrates using substrate misrecognition; P450 oxidative reactions using electrochemical methods; electron transfer to P450 by redox proteins; hydroxylation of 1,8-cineole by P450cin; and peroxygenation by unspecific peroxygenases using H2O2. The topics covered are relevant to P450 researchers, professors and students from a variety of disciplines ranging from pharmacology, toxicology and microbiology to chemistry.

The purpose of Protein-Protein Recognition is to bring together concepts and systems pertaining to protein-protein interactions in a single unifying volume. In the light of the information from the genome sequencing projects and the increase in structural information it is an opportune time totry to make generalizations about how and why proteins form complexes with each other. The emphasis of the book is on heteromeric complexes (complexes in which each of the components can exist in an unbound state) and will use well-studied model systems to explain the processes of formingcomplexes. After an introductory section on the kinetics, thermodynamics, analysis, and classification of protein-protein interactions, weak, intermediate, and high affinity complexes are dealt with in turn. Weak affinity complexes are represented by electron transfer proteins and integrincomplexes. Anti-lysozyme antibodies, the MHC proteins and their interactions with T-cell receptors, and the protein interactions of eukaryotic signal transduction are the systems used to explain complexes with intermediate affinities. Finally, tight binding complexes are represented by theinteraction of protein inhibitors with serine proteases and by nuclease inhibitor complexes. Throughout the chapters common themes are the technologies which have had the greatest impact, how specificity is determined, how complexes are stabilized, and medical and industrial applications.

Radicals for Life: the Various Forms of Nitric Oxide provides an up-to-date overview of the role of nitrosocompounds and nitrosyl-iron complexes in physiology. Nitrosocompounds can be considered as stabilised forms of nitric oxide, one of the most important regulatory molecules in physiology today. Many nitrosocompounds share some of the physiological functions of nitric oxide, and may be formed inside living organisms. This is the first book to be published that is dedicated to the role of such nitrosocompounds in physiology, with particular emphasis on the nitrosocompounds that are endogenously formed in higher organisms and humans. Points of discussion include: physical and chemical properties of the compounds, the main chemical pathways in vivo, as well as the physiological effects that have been recognised to date. Each of the nineteen chapters is written by distinguished specialists in the field, well known for their original and important contributions to the subject. Also included are results from a wide range of studies in vitro, in cell cultures, animal models and human volunteers. Examples of alternative forms of nitric oxide, with special emphasis on their protective role against widespread human diseases like atherosclerosis, Alzheimer's disease, diabetes, sexual dysfunction, and renal insufficiency to stroke and ischemia are also included. - First monograph to consider and provide an overview of endogenous nitrosocompounds and nitrosyl-iron complexes - Extensive bibliographic references, written by specialists of human physiology - Providing high scientific quality with a focus on implications for human diseases
