Book Description
Functions of Alternative Terminal Oxidases is a collection of papers from the 11th meeting of the Federation of European Biochemical Societies in Copenhagen in 1977. The book opens with a review of the alternate electron transport mechanism to the main phosphorylating respiratory chain. One paper presents the respiration of mutant stains of Neurospora crassa treated with chloramphenicol that results in three distinct pathways distinguishable by the use of inhibitors. Another paper outlines the testing methods to determine the parameters controlling cyanide-insensitive respiration in Acanthamoeba castellanii and notes the physiological function of this insensitivity. The book then explains that this phenomenon of cyanide-insensitive respiration is common among yeasts, and such pathway of electron transport to oxygen that is insensitive to cyanide or antimycin is well founded in many higher plants and microorganisms. One paper then investigates the terminal oxidases found in two stages in the life cycle of trypanosomes, which cause African sleeping sickness. Another paper notes that a study of the energy metabolism of End. magnusii, a kind of yeast, showed no glucose repression, no alternative oxidation pathway, and no cyanide-insensitive pathway was normally present. The text will be of interest to those whose work involves these organisms, and to researchers, professors, and students whose disciplines are in developmental biology, micro-biology, or cellular biology.

Book Description
Rapid developments in molecular and systems biology techniques have allowed researchers to unravel many new mechanisms through which plant cells switch over to alternative respiratory pathways. This book is a unique compendium of how and why higher plants evolved alternative respiratory metabolism. It offers a comprehensive review of current research in the biochemistry, physiology, classification and regulation of plant alternative respiratory pathways, from alternative oxidase diversity to functional marker development. The resource provides a broad range of perspectives on the applications of plant respiratory physiology, and suggests brand new areas of research. Other key features: written by an international team of reputed plant physiologists, known for their pioneering contributions to the knowledge of regular and alternative respiratory metabolism in higher plants includes step-by-step protocols for key molecular and imaging techniques advises on regulatory options for managing crop yields, food quality and environment for crop improvement and enhanced food security covers special pathways which are of key relevance in agriculture, particularly in plant post-harvest commodities Primarily for plant physiologists and plant biologists, this authoritative compendium will also be of great value to postdoctoral researchers working on plant respiration, as well as to graduate and postgraduate students and university staff in Plant Science. It is a useful resource for corporate and private firms involved in developing functional markers for breeding programs and controlling respiration for the prevention of post-harvest losses in fruit, vegetables, cut flowers and tubers.

Book Description
Mitochondria in plants, as in other eukaryotes, play an essential role in the cell as the major producers of ATP via oxidative phosphorylation. However, mitochondria also play crucial roles in many other aspects of plant development and performance, and possess an array of unique properties which allow them to interact with the specialized features of plant cell metabolism. The two main themes running through the book are the interconnection between gene regulation and protein function, and the integration of mitochondria with other components of plant cells. The book begins with an overview of the dynamics of mitochondrial structure, morphology and inheritance. It then discusses the biogenesis of mitochondria, the regulation of gene expression, the mitochondrial genome and its interaction with the nucleus, and the targeting of proteins to the organelle. This is followed by a discussion of the contributions that mutations, involving mitochondrial proteins, have made to our understanding of the way the organelle interacts with the rest of the plant cell, and the new field of proteomics and the discovery of new functions. Also covered are the pathways of electron transport, with special attention to the non-phosphorylating bypasses, metabolite transport, and specialized mitochondrial metabolism. In the end, the impact of oxidative stress on mitochondria and the defense mechanisms, that are employed to allow survival, are discussed. This book is for the use of advanced undergraduates, graduates, postgraduates, and beginning researchers in the areas of molecular and cellular biology, integrative biology, biochemistry, bioenergetics, proteomics and plant and agricultural sciences.

Book Description
Molecular hydrogen (H2) is an important molecule in the metabolism of diverse microorganisms. It is used either as energy source or for the disposal of reducing equivalents depending on environmental conditions. Furthermore, H2 transmits energy between different species within microbial communities. The enzymes that split or evolve H2 are called hydrogenases and these metalloproteins can be divided into three phylogenetically unrelated classes distinguishable by the metal composition of their active sites, namely [Fe]-, [FeFe]-, and [NiFe]- hydrogenases. Following a century of hydrogenase research, it is now possible to isolate, handle, and investigate these fragile enzymes. There have been numerous advances in understanding the regulation, function, structures, and maturation of these enzymes, as well as their involvement in important processes such as microbial pathogenesis and biogeochemical cycling. The employment of hydrogenases and hydrogenase-based applications could also potentially facilitate the world’s transition to a future sustainable H2-based energy economy.

Book Description
The opportunistic pathogen Pseudomonas aeruginosa offers a rich variety of biologically relevant topics to explore and serves as a model system to understand the interactions of Gram-negative bacteria with human hosts. The organism adapts readily to most environments. It has a large and variable genome with a great deal of metabolic potential. P. aeruginosa encodes a variety of regulatory systems to fine tune gene expression and integrate environmental signals. This organism can infect both plants and animals and produces a plethora of enzymes and factors that can overcome host defenses. Moreover, it has the ability to change between the states of a sedentary colonizer to an invasive and highly motile organism. Clinically, the bacterium is resistant to many antibiotics making it difficult to treat and impossible to eradicate from the lungs of patients with cystic fibrosis. Intrinsic antibiotic resistance combined with an armamentarium of tissue degradative enzymes makes it imperative to possess a comprehensive understanding of the biology, genetics and pathogenesis of this organism so that novel therapeutics based on virulence product neutralization can be designed and implemented. This Research Topics issue will be devoted to updating the current understanding of P. aeruginosa systems as they relate to its different lifestyles in different environments. The underlying theme is to provide broad overviews and to integrate protein structure-function and gene regulation as it relates to the biology of this bacterium.

Book Description
This volume collects the papers presented at the "Second Euro pean Conference on Phagocytic Leucocytes" which was held in Trieste, September 15-18, 1980. The Conference was the continuation of the thread of a discourse initiated with the "First European Conference on Phagocytic Leucocytes," which was held also in Trieste in 1976. In fact, in both Conferences the biochemical aspects of the basic functions of phagocytes--that is movement, metabolism, secretion, and bactericidal activity--were mainly emphasized. In the Second Confer ence, two additional subjects were also dealt with, and those are the tumoricidal activity of phagocytes and the clinical aspects of phagocyte functions. In connection with the latter subject a "Round Table on the Clinical Application of Leucocyte Function Tests" was held during the Conference, and the proceedings are reported in this book in the hope that they may be useful to those who are interested in the relationship between phagocytes and diseases. The number of papers which are being published concerning the phagocytic process is such that one wonders whether publication of a new book in this field is necessary. However, the philosophy which inspired the edi ting of this book differs from that underlying publication of origi nal articles in scientific journals. We started from the common notion that the real progress of our knowledge is not necessarily proportional to the amount of published material in that specific field.
