This volume contains up-to-date information on aldehyde dehydrogenase, alcohol dehydrogenase, short- and medium-chain dehydrogenase, and reductases. Sixty-nine contributions provide a wide variety of information on enzymology, molecular biology, and metabolic aspects of these carbonyl metabolizing oxidoreductases. Much new information is provided, including previously unreported three-dimensional structures of enzymes and new aspects of gene regulation, along with sequence alignments, metabolism and enzyme mechanisms.
The largest collection of articles on the three major gene families, this work ranges from enzymology to molecular biology to physiological implications. The three gene families are related in that the enzymes catalyse the NAD(P) dependent oxidation or reduction of carbonyl containing substrates. The substrates are important in diverse areas such as alcoholism, diabetes and cancer related problems as well as simple detoxification. The scope of the chapters, contributed by leading international scientists, is wide and covers gene regulation to enzyme mechanisms and protein structure. This is the only publication dealing in such depth with just three gene families. An important reference for researchers in toxicology and molecular biology.
Food and raw material for its production was generally produced via the traditional agriculture. On the other hand, novel chemicals were manufactured in the laboratory or extracted from plant and animal sources. However, as the world population is steadily in creasing, there is a decrease in traditional agriculture productivity and concerns are also expressed over the damage inflicted to the environment and restrictions that might be en forced in food production. At the same time, there is an increasing demand for high qual ity agricultural products as well as for food ingredients related to both the traditional or newly discovered nutrients or phytochemicals. Trends and developments,~n the ...
The ocean plays a central role in the life and development of human kind. Besides space for navigation and trade (roughly 10 billion tons of commodities are transported across the oceans each year), the provision of biological and non-living resources is the most important service of the marine ecosystems. Yet, these ecosystems are increasingly impeded by human activities and interventions. Human and naturally induced changes in climate are buffered by the ocean, but its capacity to compensate the increase of CO2 in the atmosphere is at its limit. The increase of global temperatures and the decrease of oxygen concentration and pH are severe stressors for aquatic species and thus for the whol...
In the forty years since melatonin's isolation and characterization, a large and multifaceted database has accrued. This book documents the diverse research contributions of most of the major laboratories in the field of melatonin research, as presented in a special conference to mark the 40 year anniversary of the isolation and chemical identification of this hormone. In addition, many chapters by younger scientists provide an exciting glimpse of where melatonin research is heading in the future.
Cytokines had been characterized in the early eighties as communication mole cules between immune cells, and between immunocytes and other peripheral cells, such as fibroblasts and endothelial cells. They play a key role in the regulation of the immune response and the coordination of the host response to infection. Based on these biological properties, nobody would have predicted that one decade later cytokines would burst upon neurosciences and permeate into several avenues of current research. In neurology, the connection between cytokines and inflammation, and the demonstration of a pivotal role of some of these molecules in cell death by apoptosis, prompted the investigation of their in...
Inhaltsangabe:Introduction: Metabolic reduction is the counterpart to oxidative pathways and plays an important role in the phase-I metabolism of carbonyl group bearing substances. Carbonyl reduction means the formation of a hydroxy group from a reactive aldehyde or ketone moiety and is generally regarded as an inactivation or detoxification step since the resulting alcohol is easier to conjugate and to eliminate. Not only are these carbonyl-containing compounds widespread in the environment and enter the body as xenobiotics and environmental pollutants, but they can also be generated endogenously through normal catabolic oxidation and deamination reactions. Many endogenous compounds such as...
Progress in Nucleic Acid Research and Molecular Biology provides a forum for discussion of new discoveries, approaches, and ideas in molecular biology. It contains contributions from leaders in their fields and abundant references.
Since the inception of these meetings in 1982, they have always been a satellite of the International Society for Biomedical Research on Alcoholism meeting. At our 1992 meeting in Dublin we learned that the next ISBRA meeting would be held in Brisbane, of all our previous meetings, I was very concerned Australia. As the scientific organizer about holding a meeting in the Southern Hemisphere for fear that many of our potential participants would not travel that far. I am pleased to say that I was proven to be incorrect. Nearly 90 scientists from a dozen countries participated at our seventh conference. At this meeting, like at all our previous ones, much new information about the three enzyme...
This volume contains the proceedings of the Ninth Meeting of the "International Study Group for Tryptophan Research" (lSTRY), held at the University of Hamburg, Germany, from October 10 to 14, 1998. At this meeting the recent developments in the field of tryptophan research were presented by leading researchers from all over the world in 81 oral and 48 poster contri butions. Research on tryptophan and its derivatives provides an inexhaustible subject. At the conference we tried to compose a multifacetted picture of the recent investiga tions through contributions from the major disciplines involved. Thus, we tried to strike a balance between basic research topics and clinical, nutritional or...
