Published in 2014, Protein Deimination in Human Health and Disease was the first book on this novel post-translational modification, in which selected positively-charged arginine amino acids are converted to neutral citrulline amino acids by the peptidyl-arginine deiminase (PAD) family of enzymes. This area of research continues to expand rapidly, necessitating the need for this second edition. Chronicling the latest inflammatory, epigenetic, neurodegenerative, and carcinogenic processes, Protein Deimination in Human Health and Disease, Second Edition, updates the latest advances in deimination research, including new information on PAD enzyme structure and activity, and how PAD knock-out animals are being used to study known and newly-discovered links to various human diseases. The first edition outlined what was known about citrullinated proteins in normal tissues such as skin and hair, as well as in maladies such as rheumatoid arthritis (RA), multiple sclerosis (MS), Alzheimer's disease (AD), glaucoma, peripheral nerve injury, neonatal hypoxic brain damage, and breast cancer. This second edition addresses numerous additional disorders such as diabetes, asthma, traumatic brain injury, inflammatory bowel disease, lupus, bone disease, heart failure, fronto-temporal dementia, and prostate and colon cancer. It also provides updates on the deimination research covering the three seminal diseases first linked to this process (RA, MS and AD), and details how auto-antibodies against citrullinated proteins contribute to disease. In addition, new hypotheses on the possible pathologic mechanisms of citrullinated myelin basic protein and glial fibrillary acidic protein are also proposed. This second edition also outlines the latest developments in therapeutic strategies, including the use of new PAD antagonists and innovative techniques such as micro-vescicles and stem cells as possible mechanisms to treat these conditions.

Immobilization of Enzymes and Cells (Hardcover, 2nd ed. 2006): Jose M. Guisan Immobilization of Enzymes and Cells (Hardcover, 2nd ed. 2006)

R4,078 Discovery Miles 40 780 Ships in 18 - 22 working days

Enzymes and whole cells are able to catalyze the most complex chemical processes under the most benign experimental and environmental conditions. In this way, enzymes and cells could be excellent catalysts for a much more sustainable chemical industry. However, enzymes and cells also have some limitations for nonbiological applications: fine chemistry, food chemistry, analysis, therapeutics, and so on. Enzymes and cells may be unstable, difficult to handle under nonconventional conditions, poorly selective toward synthetic substrates, and so forth. From this point of view, the transformation-from the laboratory to industry-of chemical processes catalyzed by enzymes and cells may be one of the most complex and exciting goals in biotechnology. For many industrial applications, enzymes and cells have to be immobilized, via very simple and cost-effective protocols, in order to be re-used over very long periods of time. From this point of view, immobilization, simplicity, and stabilization have to be strongly related concepts. Over the last 30 years, a number of protocols for the immobilization of cells and enzymes have been reported in scientific literature. However, only very few protocols are simple and useful enough to greatly improve the functional properties of enzymes and cells, activity, stability, selectivity, and related properties.

Glycosyltransferases (GTs) are essential for the biosynthesis of complex glycoconjugates and are powerful tools to study the functions of complex glycans in health, development and disease. Complex glycoconjugates, such as glycoproteins, proteoglycans and glycolipids, are assembled by GTs which synthesize specific linkages between sugars or sugars and protein. This is in contrast to the non-specific or less specific chemical glycation reactions, transglycosylation and reverse glycosylation reactions. Glycosyltransferases: Methods and Protocols contains a wide range of studies, methods and protocols which form a solid basis for investigations of the role and mechanisms, biology and pathology involving GTs. Written in the successful Methods in Molecular Biology (TM) series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible protocols, and notes on troubleshooting and avoiding known pitfalls. Authoritative and easily accessible, Glycosyltransferases: Methods and Protocols is a vital contribution to glycobiology and glycopathology, and to applications of these enzymes in biotechnology and drug development. It will prove invaluable to students, postdoctoral fellows, and senior scientists carrying on research of GTs that has been intensified over the last years.

This comprehensive volume completes Frederic Holmes's notable and detailed biography of Hans Krebs, from the investigator's early development through the major phase of his groundbreaking investigation, which lay the foundations upon which the modern structure of intermediary metabolism is built. With access to Krebs's research notebooks as well as to Krebs himself through more than five years of personal interviews, the author provides an insightful analysis of Hans Krebs and of the scientific process as a whole. The first volume, published in 1991, covered Krebs's formative years in Germany, his work with Otto Warburg, and his discovery of the urea cycle in 1932. This second volume reconstructs the investigative pathway and the professional and personal life of Hans Krebs, from the time of his arrival in England in 1933 until 1937, when he made the discovery for which he is best known-the formulation of the citric acid cycle. Holmes portrays Krebs's activity at the intimate level of daily interactions of thought and action, from which the characteristic patterns of scientific creativity can best be seen. Holmes's fascinating portrait of Krebs integrates the great scientist's investigative pathways with his personal life. The result is an illuminating analysis of both man and scientist that will be of interest to biochemists and historians of science.

Rab GTPases now comprise a family of >63 members. They are emerging as the key hub element controlling the membrane architecture of eukaryotic cells. They are intimately involved in vesicle targeting and fusion in both the endocytic and exocytic pathways and direct the assembly and disassembly of protein complexes that include regulators (GEFs and GAPs), effectors (tethers/motors) and fusion components (SNAREs) that control membrane targeting and fusion. During the last 3 years the field has virtually exploded with the identification and characterization of many new Rab proteins and their effectors.
Our understanding of how Rab GTPases control membrane function remains at its infancy. This volume of MIE provides a wealth of new concepts, approaches and tools to study Rab proteins in the test tube and in living cells that will be of strong benefit to both established laboratories and new investigators in the field to elucidate Rab GTPase function in cellular development, differentiation and proliferation.

Bioethanol has been recognized as a potential alternative to petroleum-derived transportation fuels. Even if cellulosic biomass is less expensive than corn and sugarcane, the higher costs for its conversion make the near-term price of cellulosic ethanol higher than that of corn ethanol and even more than that of sugarcane ethanol. Conventional process for bioethanol production from lignocellulose includes a chemical/physical pre-treatment of lignocellulose for lignin removal, mostly based on auto hydrolysis and acid hydrolysis, followed by saccharification of the free accessible cellulose portions of the biomass. The highest yields of fermentable sugars from cellulose portion are achieved by means of enzymatic hydrolysis, currently carried out using a mix of cellulases from the fungus Trichoderma reesei. Reduction of (hemi)cellulases production costs is strongly required to increase competitiveness of second generation bioethanol production. The final step is the fermentation of sugars obtained from saccharification, typically performed by the yeast Saccharomyces cerevisiae. The current process is optimized for 6-carbon sugars fermentation, since most of yeasts cannot ferment 5-carbon sugars. Thus, research is aimed at exploring new engineered yeasts abilities to co-ferment 5- and 6-carbon sugars. Among the main routes to advance cellulosic ethanol, consolidate bio-processing, namely direct conversion of biomass into ethanol by a genetically modified microbes, holds tremendous potential to reduce ethanol production costs. Finally, the use of all the components of lignocellulose to produce a large spectra of biobased products is another challenge for further improving competitiveness of second generation bioethanol production, developing a biorefinery.

The Ras superfamily (>150 human members) encompasses Ras GTPases involved in cell proliferation, Rho GTPases involved in regulating the cytoskeleton, Rab GTPases involved in membrane targeting/fusion and a group of GTPases including Sar1, Arf, Arl and dynamin involved in vesicle budding/fission. These GTPases act as molecular switches and their activities are controlled by a large number of regulatory molecules that affect either GTP loading (guanine nucleotide exchange factors or GEFs) or GTP hydrolysis (GTPase activating proteins or GAPs). In their active state, they interact with a continually increasing, functionally complex array of downstream effectors.
Since the last Methods in Enzymology volume on this topic in 2000, Rho GTPases have continued to receive a huge amount of attention. The human genome sequence has revealed the full extent of the Rho GEF and Rho GAP families (over 80 members for each) and the challenge of identifying the molecular interactions and cellular pathways influenced by each of these regulators is a daunting prospect. This new volume describes some of the methods currently being used to examine Rho family GTPase regulation at the biochemical and cellular level.
*Describes the methods currently being used to examine Rho family GTPase regulation at the biochemical and cellular levels.
*Includes new imaging techniques that revolutionize the ability to visualize GTPase activities.

Metal toxicity and deficiency are both common abiotic problems faced by plants. While metal contamination around the world is a critical issue, the bioavailability of some essential metals like zinc (Zn) and selenium (Se) can be seriously low in other locations. The list of metals spread in high concentrations in soil, water and air includes several toxic as well as essential elements, such as arsenic (As), cadmium (Cd), chromium (Cr), aluminum (Al), and selenium (Se). The problems for some metals are geographically confined, while for others, they are widespread. For instance, arsenic is an important toxic metalloid whose contamination in Southeast Asia and other parts of world is well documented. Its threats to human health via food consumption have generated immense interest in understanding plants' responses to arsenic stress. Metals constitute crucial components of key enzymes and proteins in plants. They are important for the proper growth and development of plants. In turn, plants serve as sources of essential elements for humans and animals. Studies of their physiological effects on plants metabolism have led to the identification of crucial genes and proteins controlling metal uptake and transport, as well as the sensing and signaling of metal stresses. Plant-Metal Interactions sheds light on the latest development and research in analytical biology with respect to plant physiology. More importantly, it showcases the positive and negative impacts of metals on crop plants growth and productivity.

The first contribution presents coumarins, the largest group of 1-benzopyran derivatives found in plants. Coumarin chemistry remains one of the major interest areas of phytochemists, especially because of their structural diversity and medicinal properties, along with the wide-ranging bioactivities of these compounds, inclusive of analgesic, anticoagulant anti-HIV, anti-inflammatory, antimicrobial, antineoplastic, antioxidant, and immunomodulatory effects. The second contribution presents a comprehensive survey of the many aspects of PAD biochemistry and physiology. The third contribution gives a comprehensive overview of secondary metabolites from higher fungi, with more than 700 references highlighting the isolation, structure elucidation, biological activities, chemical synthesis, and biosynthesis of pigments, nitrogen-containing compounds, and terpenoids from mushrooms.
