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 Provides an extremely useful reference for the experienced research scientist Covers biosynthesis of Polyketides, Tarpenoids, Aminocoumarins and Crabohydrates

Authored by leading experts in the enzymology of natural product biosynthesis, this completely revised and updated edition provides a description of the types of natural products, the biosynthetic pathways that enable the production of these molecules, and an update on the discovery of novel products in the post-genomic era. Although some 500 000 – 600 000 natural products have been isolated and characterized over the past two centuries, there may be a 10-fold greater inventory awaiting immediate exploration based on biosynthetic gene cluster predictions. The approach of this book is to codify the chemical logic that underlies each natural product structural class as they are assembled from building blocks of primary metabolism. This second edition integrates many new findings into the sets of principles of the first edition that parsed categories of natural product chemistries into the underlying enzymatic mechanisms and the catalytic machinery for building the varied and complex end product metabolites. New chapters include evaluation of a core set of thermodynamically activated but kinetically stable metabolites that power both primary and secondary metabolic pathways. Also, after decades of uncertainty about the existence of various pericyclase classes, a series of genome mining, heterologous expression, and enzymatic activity characterization have validated a plethora of pericyclases over the past decade. The several types of pericyclases are involved in biosynthetic complexity generation of almost every major category of natural products. This text will serve as a reference point for chemists of every subdiscipline, including synthetic organic chemists and medicinal chemists. It will also be valuable to bioinformatic and computational biologists, pharmacognocists and chemical ecologists, and bioengineers and synthetic biologists.

This book was developed from the proceedings of the American Chemical Society, Division of Agricultural & Food Chemistry, subdivision of Natural Products Symposium "Biosynthesis and Metabolism of Secondary Natural Products" held in Atlanta, Georgia, April 1991. The objective of the conference was to bring together people from apparently diverse fields, ranging from biotechnology, metabolism, mechanistic organic chemistry, enzymology, fermentation, and biosynthesis, but who share a common interest in either the biosynthesis or the metabolism of natural products. It is our intention to help bridge the gap between the fields of mechanistic bio-organic chemistry and biotechnology. Our thanks go to Dr. Henry Yokoyama, co-organizer of the symposium, the authors who so kindly contributed chapters, the conference participants, and to those who assisted in the peer review process. We also thank the financial supporters of the symposium: ACS/AGFD, NIH General Medical Sciences, and the agricultural, pharmaceutical, biotechnology, and chromatography companies. A full list of the supporting corporations and institutions is given on the following page. Pharma-Tech and P.C., Inc. are manufacturers of instrumentation for high-speed countercurrent chromatography. We thank the Agricultural Research Service and the U. S. Department of Agriculture for granting me permission to co-organize the conference and for us to complete the book. Richard J. Petroski Susan P.

The fifth edition of the Kirk-Othmer Encyclopedia of Chemical Technology builds upon the solid foundation of the previous editions, which have proven to be a mainstay for chemists, biochemists, and engineers at academic, industrial, and government institutions since publication of the first edition in 1949. The new edition includes necessary adjustments and modernisation of the content to reflect changes and developments in chemical technology. Presenting a wide scope of articles on chemical substances, properties, manufacturing, and uses; on industrial processes, unit operations in chemical engineering; and on fundamentals and scientific subjects related to the field. The Encyclopedia describes established technology along with cutting edge topics of interest in the wide field of chemical technology, whilst uniquely providing the necessary perspective and insight into pertinent aspects, rather than merely presenting information. * Set began publication in January 2004 * Over 1,000 articles * More than 600 new or updated articles 27 volumes
