Book Description
This book serves as a tool to expand the knowledge of researchers in the discipline of microbiology and biochemistry encompassing the fields of molecular biology, structural biology, and crystallography for the two very important industrial enzymes: proteases and lipases. In addition it covers the fermentation technology for the production of locally isolated microbial lipases and proteases. This book presents work done in our laboratory which extensively reviews two major types of lipases and proteases: thermostable and/or organic-solvent tolerant including a chapter on cold-active and organic solvent tolerant lipase and protease isolated from Antarctica. Detailed descriptions on the isolation methods, protein production, protein characterisation, and molecular cloning are discussed. Further works on structural biology of both proteases and lipases which include docking, molecular modification as well as protein crystallisation are also presented. For protein crystallographers, this book highlights a novel discovery of high temperature crystallisation of lipase.In addition, this book also offers a chapter on the cultivation strategy of lipase and protease in yeast expression systems and its bio-reactor studies. In short, this book is an all-in-one quick source of reference for researchers who want to have a quick grasp of understanding on many aspects of enzyme production, starting from the isolation and expression of the enzyme until crystallisation and structure elucidation of the protein.

Book Description
From reviews to the first edtion: "Bornscheuer and Kazlauskas have set out, and succeeded, in producing a definitive manual on hydrolytic enzymes (especially lipases, esterases, and proteases) for organic chemists. This is quite simply the best book of its type and can be unreservedly recommended to organic chemists who have an interest in using hydrolytic enzymes in synthesis." (Nicholas J. Turner, University of Edinburgh) "The book is an indispensable source of information on the use of hydrolases in organic synthesis. The subject matter is very well set out, and the chapters are clearly written and presented from a critical viewpoint. Bornscheuer and Kazlauskas have succeeded admirably in describing the capabilities and limitations of the use of hydrolytic enzymes and in critically evaluating them. No library should be without the book." (Fritz Theil, WITEGA Angewandte Werkstoff-Forschung GmbH, Berlin) The second edition of this extremely successful and well-proven book presents recent developments in the use of hydrolases for organic synthesis, reflecting in particular the enormous progress made in enzyme discovery and optimization with a new chapter on "Protein Sources and Optimization of Biocatalyst Performance". The renowned authors survey the stereoselective reactions of hydrolases, especially lipases, esterases and proteases, giving researchers an overview of what has worked in the past so that they can judge how to solve their own synthetic problems. In total, the book contains over one thousand chemical structures, rounded off by some 1,800 invaluable references.

Book Description
The secretions of the exocrine pancreas provide for digestion of a meal into components that are then available for processing and absorption by the intestinal epithelium. Without the exocrine pancreas, malabsorption and malnutrition result. This chapter describes the cellular participants responsible for the secretion of digestive enzymes and fluid that in combination provide a pancreatic secretion that accomplishes the digestive functions of the gland. Key cellular participants, the acinar cell and the duct cell, are responsible for digestive enzyme and fluid secretion, respectively, of the exocrine pancreas. This chapter describes the neurohumoral pathways that mediate the pancreatic response to a meal as well as details of the cellular mechanisms that are necessary for the organ responses, including protein synthesis and transport and ion transports, and the regulation of these responses by intracellular signaling systems. Examples of pancreatic diseases resulting from dysfunction in cellular mechanisms provide emphasis of the importance of the normal physiologic mechanisms.

Book Description
Microbial lipases are industrially important and have gained their attention due to their stability, selectivity, and broad substrate specificity. Lipases are used as a medicine and also aid in indigestion, heartburn, allergy to gluten in wheat products (celiac disease), Crohn's disease, and cystic fibrosis. This new volume, Lipase: An Industrial Enzyme Through Metagenomics, considers the industrial demand for new sources of lipases with different catalytic characteristics that stimulate the growth and development isolation of new strains. The volume narrates the challenging metagenomic approach with the isolation of the lipase gene, its cloning into Escherichia coli, culture of the recombinant bacteria, and extraction and assessment of the lipase enzyme. Lipase-producing bacteria have been found in different habitats, such as industrial wastes, vegetable oil processing factories, dairy plants, and soils contaminated with oil and oil seeds among others. This volume is the effort of the authors to document the scientific findings carried out over the last eight years in the area of un-culturable soil microorganisms. The book presents the physicochemical features of lipases and their specific applications in different commercial industries. The in-depth study looks at metagenomics for lipases from all angles and provides a truly informative resource. It describes the biochemical characterization of lipase enzymes with the high activity in the presence of 1% tributyrin. The book also highlights the maximum activity of the enzyme at temperature 37�C and pH 7.5 in the presence of the divalent cations Ca2+, Mn2+, Zn2+and Fe2+. CTAB, gum arabic, NaCl and organic solvents like ethanol, 1-propanol, acetone, acetonitrile, glycerol and DMSO. A wide review has been presented in the book on lipase enzymes purified from a large collection of microbes present in soil, seawater, waste-dumping sites, animal systems (including human beings), and the atmosphere. Stability of enzymes over changing environments of the industry is indeed a big issue, and the book deals at length with the changing temperatures and pH and metal ion concentrations. The book also highlights the antifungal and antibacterial activity of the lipase enzyme.
