The Biosynthesis of Mycotoxins: A Study in Secondary Metabolism focuses on the biosynthetic analysis of mycotoxins, which are inherently a heterogeneous group of metabolites that are formed along the terpene route and the route polyketide, as well as from amino acids. This book discusses the unique biological properties and structural complexity of the highly specialized secondary microbial metabolites. Organized into 12 chapters, this book starts with an overview of the characteristics of secondary metabolites, including their problematic function and the combination of their structural diversity with their restricted biological occurrence. This text then explains the sporadic occurrence of the mycotoxins as fungal metabolites. Other chapters explore ergochromes, which are a group of light yellow mycotoxins that are isolated from ergot, mold fungi, and lichens. The final chapter discusses the biosynthesis of several unrelated fungal metabolites for which toxicological data are reported. Biochemists, organic chemists, mycologists, enzymologists, plant pathologists, toxicologists, and graduate students will find this book useful.

The ingestion of feed containing mycotoxins has serious adverse effects on the health of farm animals, contributing to reduced weight gain, lower reproductivity, damage to the immune system, severe illnesses, and even death. Mycotoxins formed in animal feedstuffs depend on the presence of specific strains of filamentous fungi or molds and are strongly influenced by environmental factors such as temperature and humidity. This book considers the biological nature of mycotoxin formation, the chemical and biological methods of analysis, as well as the extensive range of substrates capable of supporting the growth of toxigenic fungi. The book also provides extensive coverage of the mycotoxicoses of farmed animals and the current state of research into the control and detoxification of mycotoxins. All researchers interested in mycotoxins and their effects on animals will find important information in this book.

​Fungi produce many chemically diverse secondary metabolites whose biological roles largely remain elusive. Within the increasing number of sequenced fungal genomes several important genes involved in secondary metabolite formation have been identified. Most of these genes are clustered and their coordinated transcription is controlled in a complex way by both narrow pathway-specific regulators as well as broad global transcription factors responsive to environmental cues. In recent years it was discovered many of the newly identified gene clusters are silent under laboratory conditions suggesting that the biosynthetic potential of fungi is far from being exploited. Besides identifying novel bioactive metabolites from still unexplored sources, the activation of these gene clusters by several approaches may result in the discovery of new substances with antibiotic and pharmaceutical benefits. This book covers recent advances in the field of fungal secondary metabolisms ranging from methodologies to biological aspects and will include the latest knowledge on fungal molecular biology, genomics, and metabolomics. With the related volume by Professor Juan-Francisco Martin, where the most relevant and well-studied fungal secondary metabolites are compiled, this book provides a comprehensive overview of the state-of-the-art of research on fungal secondary metabolites.

In Chapter four, the results of a collaborative project to functionally characterize PrpF are presented. PrpF is an enzyme involved in the 2-methyl citrate catabolic pathway. The X-ray crystallographic study revealed strong structural homology of PrpF to the non-PLP dependent diaminopimelate epimerase, which allowed an activity of epimerization to be hypothesized and experimentally validated.

Fungal natural products are friends and foes of humans such as deleterious mycotoxins, cytotoxic, carcinogenic compounds or beneficial compounds such as antibiotics, fungicides, insecticides, antiviral and antitumor metabolites. Understanding fungal diversity and estimation of fungal species on our planet poses a great challenge to researchers. This complexity is further multiplied by secondary metabolite diversity of fungi, which requires interdisciplinary studies. It is extremely important to understand the fungal secondary metabolism to stop human, animal and plant diseases caused by fungi and harvest their valuable metabolites. Furthermore, many secondary metabolite gene clusters are silenced under laboratory conditions. It is vital to develop effective methods to activate those clusters in order to discover novel potent metabolites. This e-book is a compilation of original review articles contributed by leading fungal secondary metabolite researchers with a wide range of expertise. Important aspects of fungal secondary metabolism, including regulation, genome mining, evolution, synthetic biology and novel methods have been discussed. This book will be a great source to those people, who are interested in understanding overall structure, diversity and regulation of production of these tiny but precious chemicals.
