Provides up-to-date information on all aspects of basic and applied research on quinoproteins and quinonoid co-factors such as pyrroloquinoline quinone (PQQ) - exploring the scope, direction and potential value of investigations in this multidisciplinary field.
Since the first international meeting on Vitamin B6 involvement in catalysis took place in 1962, there have been periodic meetings every three or four years. In 1990, scientists studying another cofactor, PQQ, which had already attracted the scientific community's interest for its possible involvement in amino acid decarboxylation and reactions involving amino groups, joined forces with those investigating pyridoxal phosphate-dependent enzymes. Since then, the international PQQ/quinoproteins meetings have been held jointly. In the years following the original meeting 37 years ago in Rome, Italy, the scientific gatherings have taken place in Moscow, Russia (1966); Nagoya, Japan (1967); Leningrad (St. Petersburg), Russia (1974); Toronto, Canada (1979); Athens, Greece (1983); Turku, Finland (1987); Osaka, Japan (1990); and Capri, Italy (1996). For the first time in the history of these symposia, the international meeting was held in the United States, from October 31 through November 5, 1999, in Santa Fe, New Mexico. The scientific program focus shifted significantly beyond the original emphasis on catalysis to aspects such as cellular and genetic regulation of events involving proteins that require pyridoxal phosphate or quinoproteins. The growing awareness of the involvement of these proteins in biotechnology processes and fundamental physiological events, as well as their implication in diseases, was also represented, with emphasis on the molecular basis of these events. The meeting was symposium S278, sponsored by the International Union of Biochemistry and Molecular Biology (IUBMB).
Recent changes in the pattern of agricultural practices from use of hazardous pesticides to natural (organic) cultivation has brought into focus the use of agriculturally important microorganisms for carrying out analogous functions. The reputation of plant growth promoting rhizomicroorganisms (PGPRs) is due to their antagonistic mechanisms against most of the fungal and bacterial phytopathogens. The biocontrol potential of agriculturally important microorganisms is mostly attributed to their bioactive secondary metabolites. However, low shelf life of many potential agriculturally important microorganisms impairs their use in agriculture and adoption by farmers. The focal theme of this book is to highlight the potential of employing biosynthesized secondary metabolites (SMs) from agriculturally important microorganisms for management of notorious phytopathogens, as a substitute of the currently available whole organism formulations and also as alternatives to hazardous synthetic pesticides. Accordingly, we have incorporated a comprehensive rundown of sections which particularly examine the SMs synthesized, secreted and induced by various agriculturally important microorganisms and their applications in agriculture. Section 1 includes discussion on biosynthesized antimicrobial secondary metabolites from fungal biocontrol agents. This section will cover the various issues such as development of formulation of secondary metabolites, genomic basis of metabolic diversity, metabolomic profiling of fungal biocontrol agents, novel classes of antimicrobial peptides. The section 1 will also cover the role of these secondary metabolites in antagonist-host interaction and application of biosynthesized antimicrobial secondary metabolites for management of plant diseases. Section 2 will discuss the biosynthesized secondary metabolites from bacterial PGPRs, strain dependent effects on plant metabolome profile, bio-prospecting various isolates of bacterial PGPRs for potential secondary metabolites and non-target effects of PGPR on microbial community structure and functions. Section 3 encompasses synthesis of antimicrobial secondary metabolites from beneficial endophytes, bio-prospecting medicinal and aromatic hosts and effect of endophytic SMs on plants under biotic and biotic stress conditions.

This book is a valuable resource for biomedical researchers who focus on identifying the causes of liver diseases and food scientists targeting health-related product development. - Provides information on agents that affect metabolism and other health-related conditions in the liver - Explores the impact of composition, including differences based on country of origin and processing techniques - Addresses the most positive results from dietary interventions using bioactive foods to impact liver disease, including reduction of inflammation and improved function
The Intemational Meeting on Vitamin B6 and Carbonyl Catalysis took place on Capri, Italy from 22nd to 27th May 1994 and was organized in conjunction with the 3rd Symposium on PQQ and Quinoproteins. It was an extraordinary occasion for scientists from all over the world to meet and discuss new developments in these overlapping fields. Several sessions were dedicated to the molecular aspects of Vitamin B6 and Quinone dependent enzymes, as well as to the cellular, biomedical and nutritional aspects. The congress was inaugurated by Paolo Fasella in his capacity as General Director of Science, Research and Development of the Commission of the European Communities, with an overview on Intemational Scientific Collaboration. The scientific sessions started with a talk on the History of Vitamin B6 given by David Metzler who at the very last minute presented Esmond Snell's paper adding some personal remarks. Unfortunately, both Esmond Snell and Alton Meister had to unexpectedly cancel the trip to Capri. These proceedings contain the papers presented as oral contributions and a few selected poster presentations. The limited number of pages meant we could not publish many interesting poster presentations, including those selected for the three lively and exciting evening poster discussion sessions called by the organizers "Vino, taralli and ... discussion".
This book covers the fundamental aspects of the electrochemistry and redox enzymes that underlie enzymatic bioelectrocatalysis, in which a redox enzyme reaction is coupled with an electrode reaction. Described here are the basic concept and theoretical aspects of bioelectrocatalysis and the various experimental techniques and materials used to study and characterize related problems. Also included are the various applications of bioelectrocatalysis to bioelectrochemical devices including biosensors, biofuel cells, and bioreactors. This book is a unique source of information in the area of enzymatic bioelectrocatalysis, approaching the subject from a cross-disciplinary point of view.
Human blood performs many important functions including defence against disease and transport of biomolecules, but perhaps the most important is to carry oxygen – the fundamental biochemical fuel - and other blood gases around the cardiovascular system. Traditional therapies for the impairment of this function, or the rapid replacement of lost blood, have centred around blood transfusions. However scientists are developing chemicals (oxygen therapeutics, or “blood substitutes”) which have the same oxygen-carrying capability as blood and can be used as replacements for blood transfusion or to treat diseases where oxygen transport is impaired. Chemistry and Biochemistry of Oxygen Therapeutics: From Transfusion to Artificial Blood links the underlying biochemical principles of the field with chemical and biotechnological innovations and pre-clinical development. The first part of the book deals with the chemistry, biochemistry, physiology and toxicity of oxygen, including chapters on hemoglobin reactivity and regulation; the major cellular and physiological control mechanisms of blood flow and oxygen delivery; hemoglobin and myoglobin; nitric oxide and oxygen; and the role of reactive oxygen and nitrogen species in ischemia/reperfusion Injury. The book then discusses medical needs for oxygen supply, including acute traumatic hemorrhage and anemia; diagnosis and treatment of haemorrhages in "non-surgical" patients; management of perioperative bleeding; oxygenation in the preterm neonate; ischemia normobaric and hyperbaric oxygen therapy for ischemic stroke and other neurological conditions; and transfusion therapy in β thalassemia and sickle cell disease Finally “old”and new strategies for oxygen supply are described. These include the political, administrative and logistic issues surrounding transfusion; conscientious objection in patient blood management; causes and consequences of red cell incompatibility; biochemistry of red blood cell storage; proteomic investigations on stored red blood cells; red blood cells from stem cells; the universal red blood cell; allosteric effectors of hemoglobin; hemoglobin-based oxygen carriers; oxygen delivery by natural and artificial oxygen carriers; cross-linked and polymerized hemoglobins as potential blood substitutes; design of novel pegylated hemoglobins as oxygen carrying plasma expanders; hb octamers by introduction of surface cysteines; hemoglobin-vesicles as a cellular type hemoglobin-based oxygen carrier; animal models and oxidative biomarkers to evaluate pre-clinical safety of extracellular hemoglobins; and academia – industry collaboration in blood substitute development. Chemistry and Biochemistry of Oxygen Therapeutics: From Transfusion to Artificial Blood is an essential reference for clinicians, haematologists, medicinal chemists, biochemists, molecular biologists, biotechnologists and blood substitute researchers.
Recent determination of genome sequences for a wide range of bacteria has made in-depth knowledge of prokaryotic metabolic function essential in order to give biochemical, physiological, and ecological meaning to the genomic information. Clearly describing the important metabolic processes that occur in prokaryotes under different conditions and in different environments, this advanced text provides an overview of the key cellular processes that determine bacterial roles in the environment, biotechnology, and human health. Prokaryotic structure is described as well as the means by which nutrients are transported into cells across membranes. Glucose metabolism through glycolysis and the TCA cycle are discussed, as well as other trophic variations found in prokaryotes, including the use of organic compounds, anaerobic fermentation, anaerobic respiratory processes, and photosynthesis. The regulation of metabolism through control of gene expression and control of the activity of enzymes is also covered, as well as survival mechanisms used under starvation conditions.
