Book Description
This book highlights a new paradigm of translation control by regulatory nascent polypeptides, which is integrated into cellular regulatory systems. Translation lies in the hub of the central dogma of biology, in which the genetic information in the forms of 4-letter sentences is translated into 20-letter sentences: sequences of amino acids that constitute proteins, the functional molecules of life. The process involves a huge number of chemical reactions as well as physical movements of the ribosome along a messenger RNA and takes, on average, tens of seconds in prokaryotes and a few minutes in eukaryotes. Detailed knowledge about the progression of translation, called "elongation", only recently started to accumulate. Newly synthesized and growing polypeptides, called nascent polypeptides, can interact with the intra-ribosomal conduit, called the ribosomal exit tunnel, when they have some specific amino acid sequences, called "an arrest sequence". Such interaction leads to a halt in the elongation reaction. Resulting stalling of the ribosome on messenger RNA can affect the secondary structure and/or localization of the message in the cell, consequently leading to biological outputs such as elevation or reduction of a gene product. This book provides a first collection of knowledge focused on regulatory nascent polypeptides, which have been studied recently using diverse organisms including bacteria, plants, and animals. Readers will be impressed by a new paradigm showing that proteins can function even during the course of their biosynthesis and that the ribosome, the "factory" of protein production, interacts with and inspects its products to adjust the speed of completion of each product. Moreover, regulatory nascent polypeptides can sense or monitor physiological states of the cell and modulate its ability to arrest translation. Living organisms use such intricate control mechanisms of translational speed to regulate gene expression. This book will be a useful addition for established scientists while inspiring students and young scientists to gain deeper insights into the processes of expression of genetic information.

Book Description
New textbooks at all levels of chemistry appear with great regularity. Some fields like basic biochemistry, organic reaction mechanisms, and chemical thermodynamics are well represented by many excellent texts, and new or revised editions are published sufficiently often to keep up with progress in research. However, some areas of chemistry, especially many of those taught at the graduate level, suffer from a real lack of up-to-date textbooks. The most serious needs occur in fields that are rapidly changing. Textbooks in these subjects usually have to be written by scientists actually involved in the research which is advancing the field. It is not often easy to persuade such individuals to set time aside to help spread the knowledge they have accumulated. Our goal, in this series, is to pinpoint areas of chemistry where recent progress has outpaced what is covered in any available textbooks, and then seek out and persuade experts in these fields to produce relatively concise but instructive introductions to their fields. These should serve the needs of one semester or one quarter graduate courses in chemistry and biochemistry. In some cases the availability of texts in active research areas should help stimulate the creation of new courses.

Book Description
Biopolymer Science for Proteins and Peptides introduces all aspects of natural polymers based on structural proteins and peptides, presenting synthesis, structure, properties, proteins, materials design, and applications. The book begins by presenting the core concepts of polypeptide and protein materials, before discussing synthesis and structure in detail. The next part of the book describes physical properties, biological properties, and issues surrounding stability. Subsequent chapters offer in-depth coverage of both natural and structural protein sources, including collagen, silk, elastin, resilin, keratin, foot protein, and reflectin, and the materials that can be designed from them, such as films, fibers, textiles, microparticles, sponges and scaffolds, nanomaterials, blends, and composites. These materials are also analyzed against the available synthetic polymers. Finally, the text explores current applications and potential future developments. This is an essential resource for researchers and advanced students across a range of disciplines, including biopolymers, structural proteins, polymer science, materials science, biomaterials, biology, biotechnology, chemistry, engineering, and pharmaceutical science. In an industry setting, this is of great interest to scientists and R&D professionals working in industries with an interest in bio-based polymers for advanced applications. - Explains how biopolymers from structural proteins and peptides can be developed into materials, such as films, fibers, textiles, microparticles, sponges and scaffolds, nanomaterials, blends, and polymer composites - Provides the reader a solid understanding of the structure, synthesis, and properties - Guides the reader from sources, including collagen, silk, elastin, resilin, keratin, and reflectin, to material design and cutting-edge applications

Book Description
Assembly Instructions for Polypeptide Models provides assembly procedures for? polypeptide chains and for modeling the ?-helix and the parallel and antiparallel ?-pleated sheets. This text is divided into nine chapters and starts with a brief introduction to the basic unit of polypeptide or protein structure, which is the amino acid. The subsequent chapters deal with the components of the model system, including the torsion angles and the asymmetric ?-carbon atom. The remaining chapters present specific instructions for the construction of free amino acids, polypeptide end groups, side chain groups, secondary structures, and side chain torsion angles. This book will prove useful to protein and peptide scientists, organic chemists, and biochemists.

Book Description
Organized on a combined basis of chronology and of structural and functional hierarchy, This comprehensive text describes all aspects of proteins--biosynthesis, evolution, dynamics, ligand binding, catalysis, and energy transduction--not just their structures. This edition (first was 1984) is thoroughly updated--especially in the area of protein biosynthesis--and features end-of-chapter exercises and problems, many of which require the student to consult the cited literature in order to obtain the answer.

Book Description
Peptides are the biomolecules that consist of several amino acid chains linked through peptide bonds. This class of biomolecules is commonly found in living matter, and some of which play an imperative role in their regulation and functional activities. Peptides have been extensively applied in every aspect of human life, including cosmetics, electronics, the food industries, and pharmaceutical fields. Ultimately, peptide commercialization has become a major trend, which has been growing significantly in recent years. Viewed from the scientific perspective described above, the editor believes that the development of peptides in every aspect of human life should be accelerated. As such, this book aims to provide insight and knowledge regarding the current research that has been conducted in this field; hence, this book may encourage the reader to emphasize the importance of peptides in human life and to inspire others to identify the potency of peptides for other applications that still need further exploration. In this book, some of the compelling applications of peptides in biological and health sciences will be introduced. This book comprises an introductory chapter, along with four chapters presented by several prominent scientists who work in the field of peptide research.
