Book Description
Biological nitrogen fixation provides more than 50% of the total annual input of the essential element nitrogen to world agriculture. Thus, it is of immense agronomic importance and critical to food supplies, particularly in developing countries. This book, with chapters authored by internationally renowned experts, provides a comprehensive and detailed account of the fascinating history of the process - including the surprising discoveries of molybdenum-independent nitrogenases and superoxide-dependent nitrogenase; a review of Man's attempts to emulate the biological process - most successfully with the commercially dominant Haber-Bosch process; and the current state of the understanding art with respect to the enzymes - called nitrogenases - responsible for biological nitrogen fixation. The initial chapters use a historical approach to the biological and industrial processes, followed by an overview of assay methodologies. The next set of chapters focuses on the classical enzyme, the molybdenum nitrogenase, and details its biosynthesis, structure, composition, and mechanism of action as well as detailing both how variants of its two component proteins are constructed by recombinant DNA technology and how computational techniques are being applied. The sophisticated chemical modelling of the metal-containing clusters in the enzyme is reviewed next, followed by a description of the two molybdenum-independent nitrogenases - first, the vanadium-containing enzyme and then the iron-only nitrogenase - together with some thoughts as to why they exist! Then follows an up-to-date treatment of the clearly "non-classical" properties of the superoxide-dependent nitrogenase, which more closely resembles molybdenum-containing hydroxylases and related enzymes, like nitrate reductase, that it does the other nitrogenases. Each chapter contains an extensive list of references. This book is the self-contained first volume of a comprehensive seven-volume series. No other available work provides the up-to-date and in-depth coverage of this series and this volume. This book is intended to serve as an indispensable reference work for all scientists working in this area, including agriculture and the closely related metals-in-biology area; to assist students to enter this challenging area of research; and to provide science administrators easy access to vital relevant information.

Book Description
Biomarkers of Inborn Errors in Metabolism: Clinical Aspects and Laboratory Determination is structured around the new reality that laboratory testing and biomarkers are an integral part in the diagnosis and treatment of inherited metabolic diseases. The book covers currently used biomarkers as well as markers that are in development. Because biomarkers used in the initial diagnosis of disease may be different than the follow-up markers, the book also covers biomarkers used in both the prognosis and treatment of inherited metabolic disorders. With the introduction of expanded new-born screening for inborn metabolic diseases, an increasing numbers of laboratories are involved in follow-up confirmatory testing. The book provides guidance on laboratory test selection and interpreting results in patients with suspected inherited metabolic diseases. The book provides comprehensive guidance on patient diagnosis and follow-up through its illustrative material on metabolic pathways, genetics and pathogenesis, treatment and prognosis of inherited metabolic diseases, along with essential information on clinical presentation. Each chapter is organized with a uniform, easy-to-follow format: a brief description of the disorder and pathway; a description of treatment; biomarkers for diagnosis; biomarkers followed for treatment efficacy; biomarkers followed for disease progression; confounding conditions that can either: affect biomarker expression or mimic IEMs; other biomarkers: less established, future. - Provides comprehensive information on the tests/biomarkers selection in newborn screening and follow-up of newborn screens - Categorizes biomarkers into diagnostic markers, disease follow-up markers, and prognostic biomarkers - Covers confounding factors that can alter biomarkers in the absence of inborn errors of metabolism - Offers guidance on how to distinguish acquired causes from inborn errors of metabolism

Book Description
This book provides an overview of the world market of therapeutic enzymes and enzyme inhibitors, rare diseases, orphan drugs, the costs of drug development and therapies, and enzymes in downstream processing of pharmaceuticals. It discusses carbonic anhydrase inhibitors and their multiple drug interactions, carboxylesterase inhibitors for pharmaceutical applications, employment of inhibitors for the treatment of neurodegenerative diseases, use of engineered proteins, bioactive peptides, and fibrinolytic enzymes for thrombolytic therapy, and enzymes important for the design and development of new drugs/drug metabolites such as aldehyde oxidases and cytochrome P450 enzymes and the role the latter play in vascular biology and pathophysiology. The treatment of cancer is explored in connection with enzymatic amino acid deprivation therapies and new drugs that act as chemical degraders of oncogenic proteins. The book also introduces the resistance mechanisms of cancer. Furthermore, it provides an insight into the relationship between pathological conditions of cardiovascular disease and oxidative stress. The text also focuses on the potential use of nanoparticles as carriers for enzymes with medical relevance, computer-aided drug design for the identification of multi-target directed ligands, and the development of improved therapeutics through a glycan-“designer” approach. It concludes with an introduction to the chemoenzymatic synthesis of drugs.
