This volume, in its over two dozen chapters, constitutes an overview of the current plant toxin research. It covers from general aspects of plant toxicity to in-depth reviews of various classes of toxins, their structures, synthesis, modes of action, and upcoming uses in biotechnology. It provides an encompassing landscape of plant toxinology for both toxinologists and non-toxinologists alike.

This volume summarizes our current understanding of the structural basis of the functions of arrestin family of proteins. Arrestins were first discovered as key players in the desensitization of G protein-coupled receptors (GPCRs). Recent studies showed that arrestins are important signal transducers in their own right, organizing multi-protein complexes and scaffolding numerous signaling cascades that regulate cell proliferation, differentiation, and apoptotic death. Here arrestin functions are described primarily from the structural prospective. The book covers basal structure of arrestin proteins, receptor binding-induced conformational changes in arrestins, as well as the structure of “pre-activated” mutants. Particular focus is on the arrestin elements interacting with numerous binding partners, GPCRs and cytoplasmic signaling proteins. We expect that this information and insights will help to understand and exploit the phenomenon of signaling bias, which is a new promising direction in drug discovery. The chapters are written by the world-class specialists in the field, mostly the people who actually contributed the data discussed. The book gives coherent historical prospective and describes the most recent findings. The book would be particularly useful for scientists in academia and industry working in the fields of pharmacology, cell biology, structural biology, and drug discovery. We expect that the focus on the molecular basis of protein-protein interactions would help to develop novel tools for engaging this important type of targets for research and therapeutic purposes.

This book presents an updated discussion of the chemical composition and biological properties of the main bee products. Specific attention is focused on the beneficial biological activities of bee products in human health. Honey, royal jelly, propolis, bee pollen and bee venom are used as nutriment and in traditional medicine. Their composition is rather variable and depends on the floral source and external factors, such as seasonal, environmental conditions and processing. Bee products are rich in several essential nutrients and non essential nutrients, as sugars, minerals, proteins, free amino acids, vitamins, enzymes and polyphenols, that seem to be closely related to their biological functions. The effects of these products in nutrition, aging and age-related diseases, cancer, neurodegenerative diseases and pathogen infections are discussed.

Initially, because of the inadequate sensitivity of devices and other limitations, only major venom components of the dominant species were studied. However, in last two decades, increased sensitivity of devices and the development of new techniques, such as transcriptomics and proteomics techniques, have permitted us to analyze the structures and functions of rare species and to identify novel minor components. As a result, the number of venom components identified is increasing dramatically and the physiological functions of each component is more deeply understood. The scope of this book provides the readers an updated and comprehensive presentation on snake venoms. The subjects are divided into six sections, starting with the overview of snake venom compositions in Malaysian species, followed by description of enzymes and enzyme inhibitors contained in snake venoms. Also discussed are the effects of snake venom on cellular receptors, ion channels, blood, and lymph, as well as cytotoxic and antimicrobial molecules present in snake venoms. The last section covers the clinical consequences of envenomation and the management of snakebites using antivenins.
