Plant proteases are involved in most aspects of plant physiology and development, playing key roles in the generation of signaling molecules and as regulators of essential cellular processes such as cell division and metabolism. They take part in important pathways like protein turnover by the degradation of misfolded proteins and the ubiquitin-proteasome pathway, and they are responsible for post-translational modifications of proteins by proteolysis at highly specific sites. Proteases are also implicated in a great variety of environmentally controlled processes, including mobilization of storage proteins during seed germination, development of seedlings, senescence, programmed cell death and defense mechanisms against pests and pathogens. However, in spite of their importance, little is known about the functions and mode of actions of specific plant proteases. This Research Topic collects contributions covering diverse aspects of plant proteases research.

This book offers an overview of the diverse fields application of proteases (also termed proteolytic enzymes or proteinases), including food science and technology, pharmaceutical industries, and detergent manufacturing, reviewing the advances in the biotechnological application plant proteolytic enzymes over the last decade. In recent years, they have been the focus of renewed attention from the pharmaceutical and biotechnology industries, not only because of their activity on a wide variety of proteins but also because they are active over a range of temperatures and pHs. The main audience of this book are researchers working with plant proteases but also professionals from several industry segments such as food production and pharmaceutical companies.

This reference work provides comprehensive information about the bioactive molecules presented in our daily food and their effect on the physical and mental state of our body. Although the concept of functional food is new, the consumption of selected food to attain a specific effect existed already in ancient civilizations, namely of China and India. Consumers are now more attentive to food quality, safety and health benefits, and the food industry is led to develop processed- and packaged-food, particularly in terms of calories, quality, nutritional value and bioactive molecules. This book covers the entire range of bioactive molecules presented in daily food, such as carbohydrates, proteins, lipids, isoflavonoids, carotenoids, vitamin C, polyphenols, bioactive molecules presented in wine, beer and cider. Concepts like French paradox, Mediterranean diet, healthy diet of eating fruits and vegetables, vegan and vegetarian diet, functional foods are described with suitable case studies. Readers will also discover a very timely compilation of methods for bioactive molecules analysis. Written by highly renowned scientists of the field, this reference work appeals to a wide readership, from graduate students, scholars, researchers in the field of botany, agriculture, pharmacy, biotechnology and food industry to those involved in manufacturing, processing and marketing of value-added food products.

Following an overview on proteolytic enzyme assays, this text covers procedures on how to investigate and study proteases. It describes the use of specific restriction proteases as well as inhibitors of proteases to prevent unwanted proteolysis.

Plant protease inhibitors are diverse in number & specificity towards various proteolytic enzymes.

Methods of Soil Enzymology provides the first comprehensive set of vetted methods for studying enzymes in soils. Readers will especially benefit from the step-by-step explanation of the lab procedures, as well as background information for using these methods effectively and analyzing data. Main topics include activity assays, enzyme extraction, and synthetic enzyme complexes. Each method covered includes background informaton, step-by-step descriptions of the procedure, and special comments regarding nuances, pitfalls, and interpretation of the method. Learn the latest research methods, including enzyme extraction methods and procedures for creating synthetic enzyme complexes, as well as the newest ways to use small-scale and high-throughput methods for enzyme activity assays. Written for the researcher, but welcoming to those new to soil enzymology, the introduction includes conceptual information to orient those who are not familiar with these methods but want to use them. In the tradition of SSSA methods books, Methods of Soil Enzymology features a comprehensive approach with a focus on ease of use.

Because of increasing antibiotic resistance, stronger antibiotics are reserved for serious active infection, paving the way for a greater use of herbal antibiotics. This book helps dentists in implementing safe and effective natural medicine therapies to complement the current practice guidelines. Oral diseases continue to be a major health problem world-wide. Oral health is integral to general well-being and relates to the quality-of-life that extends beyond the functions of the craniofacial complex. The standard Western medicine has had only limited success in the prevention of periodontal disease and in the treatment of a variety of oral diseases. The dentist needs to be more informed regarding the use, safety and effectiveness of the various traditional medicines and over-the-counter products. Herbal extracts have been used in dentistry for reducing inflammation, as antimicrobial plaque agents, for preventing release of histamine and as antiseptics, antioxidants, antimicrobials, antifungals, antibacterials, antivirals and analgesics. They also aid in healing and are effective in controlling microbial plaque in gingivitis and periodontitis and thereby improving immunity. The 26 chapters in this unique book explore all the measures to utilize the natural oral care obtained from plants, animals and mineral drugs for dental care.

This volume presents current methods to detect and measure the activity of proteolytic enzymes in organisms ranging from unicellular algae to flowering plants. Chapters detail in vitro production, characterization of plant proteases, tools for in vivo modifications, proteomic approaches for identification of substrates, inhibitors and interacting partners, and the function of plant proteases in plant programmed cell death. Written in the format of the highly successful Methods in Molecular Biology series, each chapter includes an introduction to the topic, lists necessary materials and reagents, includes tips on troubleshooting and known pitfalls, and step-by-step, readily reproducible protocols. Authoritative and cutting-edge, Plant Proteases: Methods and Protocols aims to be a useful practical guide to researches to help further their study in this field.
