This book was released on 2013-10-22 with total page 429 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of carbonic anhydrase has spanned multiple generations of scientists. Carbonic anhydrase was first discovered in 1932 by Meldrum and Roughton. Inhibition by sulfanilamide was shown in 1940 by Mann and Keilin. Even Hans Krebs contributed to early studies with a paper in 1948 showing the relationship of 25 different sulfonamides to CA inhibition. It was he who pointed out the importance of both the charged and uncharged character of these compounds for physiological experiments. The field of study that focuses on carbonic anhydrase (CA) has exploded in recent years with the identification of new families and isoforms. The CAs are metalloenzymes which are comprised of 5 structurally different families: the alpha, beta, gamma, and delta, and epsilon classes. The alpha class is found primarily in animals with several isoforms associated with human disease. The beta CAs are expressed primarily in plants and are the most divergent. The gamma CAs are the most ancient. These are structurally related to the beta CAs, but have a mechanism more similar to the alpha CAs. The delta CAs are found in marine algae and diflagellates. The epsilon class is found in prokaryotes in which it is part of the carboxysome shell perhaps supplying RuBisCO with CO2 for carbon fixation. With the excitement surrounding the discovery of disease-related CAs, scientists have redoubled their efforts to better understand structure-function relationships, to design high affinity, isotype-specific inhibitors, and to delineate signaling systems that play regulatory roles over expression and activity. We have designed the book to cover basic information of mechanism, structure, and function of the CA families. The authors included in this book bring to light the newest data with regard to the role of CA in physiology and pathology, across phylums, and in unique environmental niches.

Available in PDF, EPUB and Kindle. Book excerpt: Carbonic anhydrase (CA) is a seemingly ubiquitous enzyme of profound physiological importance, which plays essential roles in respiration, acid-base homeostasis, bone resorption, calcification, photosynthesis, several biosynthetic pathways and a variety of processes involving ion, gas and fluid transfer. This enzyme, which is present in at least three gene families (a, ß, ?), has found favour as a model for the study of evolution of gene families and for site-directed mutagenesis in structure/function relationships, for protein folding and for transgenic and gene target studies. Since the early use of CA inhibitors as diuretics and in treating congestive heart failure, the enzyme has been target of considerable clinical attention. Much of this is now focused on endeavours to produce a new generation of such drugs for the effective treatment of glaucoma and other potential applications. Recent data, suggesting links between CA and various disease processes, including cancer, have stimulated further...

Download or read book Carbonic Anhydrases and Metabolism written by Claudiu T. Supuran and published by MDPI. This book was released on 2019-04-08 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: Carbonic anhydrases (CAs; EC 4.2.1.1) are metalloenzymes present in all kingdoms of life, as they equilibrate the reaction between three simple but essential chemical species: CO2, bicarbonate, and protons. Discovered more than 80 years ago, in 1933, these enzymes have been extensively investigated due to the biomedical application of their inhibitors, but also because they are an extraordinary example of convergent evolution, with seven genetically distinct CA families that evolved independently in Bacteria, Archaea, and Eukarya. CAs are also among the most efficient enzymes known in nature, due to the fact that the uncatalyzed hydration of CO2 is a very slow process and the physiological demands for its conversion to ionic, soluble species is very high. Inhibition of the CAs has pharmacological applications in many fields, such as antiglaucoma, anticonvulsant, antiobesity, and anticancer agents/diagnostic tools, but is also emerging for designing anti-infectives, i.e., antifungal, antibacterial, and antiprotozoan agents with a novel mechanism of action. Mitochondrial CAs are implicated in de novo lipogenesis, and thus selective inhibitors of such enzymes may be useful for the development of new antiobesity drugs. As tumor metabolism is diverse compared to that of normal cells, ultimately, relevant contributions on the role of the tumor-associated isoforms CA IX and XII in these phenomena have been published and the two isoforms have been validated as novel antitumor/antimetastatic drug targets, with antibodies and small-molecule inhibitors in various stages of clinical development. CAs also play a crucial role in other metabolic processes connected with urea biosynthesis, gluconeogenesis, and so on, since many carboxylation reactions catalyzed by acetyl-coenzyme A carboxylase or pyruvate carboxylase use bicarbonate, not CO2, as a substrate. In organisms other than mammals, e.g., plants, algae, and cyanobacteria, CAs are involved in photosynthesis, whereas in many parasites (fungi, protozoa), they are involved in the de novo synthesis of important metabolites (lipids, nucleic acids, etc.). The metabolic effects related to interference with CA activity, however, have been scarcely investigated. The present Special Issue of Metabolites aims to fill this gap by presenting the latest developments in the field of CAs and their role in metabolism.

Book excerpt: In this compilation, the authors address the relationship between carbonic anhydrase IX and hypoxia. Hypoxia is a key factor influencing a life-cycle of CA IX, including its expression, correct structure, stability, function, and subsequent biological implications. Hypoxia also regulates CA IX expression by post-transcriptional mechanisms through splicing and mRNA stabilization. A review is provided focusing on the sequence of elementary reactions ensuing a catalytic reaction (catalytic mechanism) of carbonic anhydrase. The closing chapter discusses carbonic anhydrases in chloroplasts, especially their location in the organelles, as well as considers their uses.

Download or read book Carbonic Anhydrase as Drug Target written by Daumantas Matulis and published by Springer. This book was released on 2019-05-21 with total page 353 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers deep insights into the thermodynamics and molecular structures of the twelve catalytically active isoforms of human carbonic anhydrase (CA) with a particular focus on inhibitor binding for drug design. X-ray crystallographic structures in combination with enzyme kinetic testing provide information on the interaction of CAs and their inhibitors, knowledge which is crucial for rational drug design. CAs are zinc carrying enzymes that catalyse the reversible interconversion of carbon dioxide and bicarbonate and are involved in numerous cellular processes. They are therefore a common target for drugs. The suppression of CA activities through inhibitory compounds has found application for example in diuretics and in glaucoma therapy. In this book methods used to determine binding thermodynamics of inhibitory compounds (Isothermal titration calorimetry, Fluorescent thermal shift assay/differential scanning fluorimetry and others) will be compared in detail. Also types and chemical synthesis of CA inhibitors, the use of antibodies against CAs as well as inhibitor application in animals are discussed.

Available in PDF, EPUB and Kindle. Book excerpt: This reference book originates from the interdisciplinary research cooperation between academia and industry. In three distinct parts, latest results from basic research on stable enzymes are explained and brought into context with possible industrial applications. Downstream processing technology as well as biocatalytic and biotechnological production processes from global players display the enormous potential of biocatalysts. Application of "extreme" reaction conditions (i.e. unconventional, such as high temperature, pressure, and pH value) - biocatalysts are normally used within a well defined process window - leads to novel synthetic effects. Both novel enzyme systems and the synthetic routes in which they can be applied are made accessible to the reader. In addition, the complementary innovative process technology under unconventional conditions is highlighted by latest examples from biotech industry.

Download or read book Enzyme Biocatalysis written by Andrés Illanes and published by Springer Science & Business Media. This book was released on 2008-06-19 with total page 398 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book was written with the purpose of providing a sound basis for the design of enzymatic reactions based on kinetic principles, but also to give an updated vision of the potentials and limitations of biocatalysis, especially with respect to recent app- cations in processes of organic synthesis. The ?rst ?ve chapters are structured in the form of a textbook, going from the basic principles of enzyme structure and fu- tion to reactor design for homogeneous systems with soluble enzymes and hete- geneous systems with immobilized enzymes. The last chapter of the book is divided into six sections that represent illustrative case studies of biocatalytic processes of industrial relevance or potential, written by experts in the respective ?elds. We sincerely hope that this book will represent an element in the toolbox of gr- uate students in applied biology and chemical and biochemical engineering and also of undergraduate students with formal training in organic chemistry, biochemistry, thermodynamics and chemical reaction kinetics. Beyond that, the book pretends also to illustrate the potential of biocatalytic processes with case studies in the ?eld of organic synthesis, which we hope will be of interest for the academia and prof- sionals involved in R&D&I. If some of our young readers are encouraged to engage or persevere in their work in biocatalysis this will certainly be our more precious reward.

Download or read book Biocatalysts for Industry written by Jonathan S. Dordick and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 333 pages. Available in PDF, EPUB and Kindle. Book excerpt: The application of enzymes or whole cells (fermentatively active or resting; microbial, plant, or animal) to carry out selective transformations of commercial importance is the central theme of industrial biocatalysis. Traditionally, biocatalysis has been in the domain of the life scientist or biochemical engineer. However, recent advances in this field have enabled biocatalytic processes to compete head on with, and in some cases out perform, conventional chemical processing. Chemo-biocatalytic systems are being developed thereby combining the most attractive features of bio catalysts, namely high specificity, with those of chemical catalysts, such as high reactivities and wide substrate specificities. Hence, synthetic chemists and chemical engineers are now beginning to use biocatalysts as highly selective reagents in chemical synthesis and processing. This book is about biocatalysts and their past, present, and potential applications in the food, pharmaceutical, and chemical industries. The con cept of the book did not emanate from a meeting. Rather, it is a compila tion of selected examples where biocatalysis either has already made a significant impact in the aforementioned industries, or has the potential to make a substantial contribution. I have been fortunate to have assembled contributions from world-class researchers in the field of biocatalysis. Their timely contributions are sincerely appreciated.
