Microbial natural products have been an important traditional source of valuable antibiotics and other drugs but interest in them waned in the 1990s when big pharma decided that their discovery was no longer cost-effective and concentrated instead on synthetic chemistry as a source of novel compounds, often with disappointing results. Moreover understanding the biosynthesis of complex natural products was frustratingly difficult. With the development of molecular genetic methods to isolate and manipulate the complex microbial enzymes that make natural products, unexpected chemistry has been revealed and interest in the compounds has again flowered. This two-volume treatment of the subject will showcase the most important chemical classes of complex natural products: the peptides, made by the assembly of short chains of amino acid subunits, and the polyketides, assembled from the joining of small carboxylic acids such as acetate and malonate. In both classes, variation in sub-unit structure, number and chemical modification leads to an almost infinite variety of final structures, accounting for the huge importance of the compounds in nature and medicine.
* Gathers tried and tested methods and techniques from top players in the field.
* In depth coverage of ribosomally-synthesised and Non-ribosomally-synthesised peptides.
* Provides an extremely useful reference for the experienced research scientist.

Ribonucleases are a ubiquitous and functionally diverse group of enzymes that have a common ability to cleave RNA. Either through scission of internal phosphodiesters, or removal of nucleotides from RNA 5' or 3' ends, ribonucleases perform essential roles in gene expression and regulation, genome replication and maintenance, host defense, stress response, and viral strategies of infection. Ribonucleases have also served as highly informative models to understand virtually every aspect of biomolecular structure and function. The fifteen chapters in this volume are written by recognized researchers in the field, and provide in-depth analyses of the major ribonuclease families. Particular focus is given to the relation of ribonuclease structure and mechanism to biological function, as well as ribonuclease dysfunction in certain disease states. Other topics include the evolutionary genetics and functional diversification of ribonucleases, engineered ribonucleases as anti-cancer agents, the mechanisms of action of artificial ribonucleases, and ribonucleases as models to understand protein folding and stability. This volume should serve as an essential reference for a broad range of researchers and educators with interests in RNA metabolism, enzymology, and gene regulation.

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.

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.

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.
* Comprehensive overview of Rab GTPase phylogeny and systems biology
* Identification and characterization of Rab GEFs, GAPs and effectors
* General methodologies to study Rab GTPase function in vitro and in vivo using biochemical, molecular and microscopy approaches

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 inducible isoforms of the enzymes cyclooxygenase (COX 2), nitric oxide synthase (iNOS) and heme oxygenase 1 (HO-1) have generated great interest as possible therapeutic targets in inflammation. This book is the first publication to address the importance of all three enzymes and the consequences of their interactions to the inflammatory process. The book brings together overviews by leading researchers in the field of the current status of knowledge of COX, NOS and HO in inflammation. These overviews cover a series of new concepts in the mechanism of inflammation. Topics include inducible enzyme involvement in inflammatory processes including the role in vascular permeability, leukocycte migration, granuloma formation, angiogenesis, neuroinflammation and algesia. New findings from transgenic animal models are reviewed. Other chapters address the importance of these enzymes in inflammatory disease states including rheumatoid arthritis, atherosclerosis and multiple sclerosis. The possibility of selective inhibitors or inducers of COX, NOS and HO, and their use in the clinic is discussed. The subject matter of this book is of interest to rheumatologists, pathologists, pharmacologists, neuroscientists and anyone with an academic interest in the mechanisms of inflammation.
