Book Description
This book provides a comprehensive review of the field of peptide biosynthesis. Individual chapters range from historical perspectives of the field to current knowledge regarding specific enzymes. Every step from gene to final bioactive peptide is covered in detail. Approximately two thirds of the book reviews the enzymes responsible for intracellular and extracellular peptide processing. Other chapters cover issues such as tissue-specific processing and the subcellular sorting of the peptides. New areas covered include the discovery, purification, characterization, and cDNA cloning of peptide processing enzymes involved with endopeptidase processing, carboxypeptidase processing, and C-terminal amidation; identification of the mammalian KEX-2 (subtilisin-like) family of proteases; identification of a second enzyme involved in C-terminal amidation; and the characterization of regulatory elements in neuropeptide genes and the associated DNA-binding proteins, such as CREB and related proteins, in addition to the Pit-1/GHF-1 family of proteins. The book's extensive coverage and 1000 references make it important reading material for new and established researchers in this rapidly expanding field.

Book Description
The concept of hormonal regulation using intercellular peptide messengers dates back to the discovery of secretin in 1902. The concept was simple: A peptide is released from specific hormone producing cells, endocrine cells, into circulation upon stimulation of the cells. The peptide hormone travels via blood to its target, the cells of which are equipped with specific receptors for high-affinity binding of the particular peptide hormone. Receptor binding subsequently elicits action of the target cells. This concept has been seriously challenged by modern biochemistry and cell biology. Thus, it is now well established that the gene of a specific peptide hormone may be expressed in different types of endocrine cells, in neurons, and in some instances also in adipocytes, myocytes, osteoblasts, and immune cells. Today, only a few hormones – including the old master hormone insulin – represent the original endocrine paradigm. Instead, the widespread cellular synthesis now raises the qu- tion of how the body maintains the regulation of its functions by peptide hormones when a hormone may originate from a variety of cells.

Book Description
The prohormone convertases (PC) 1/3 and 2 are calcium-activated eukaryotic subtilisins with low pH optima which accomplish the limited proteolysis of peptide hormone precursors within neurons and endocrine cells. In this lecture, we review the biochemistry, regulation, and roles of PC1/3 and 2 in disease, with an emphasis on the work published in the last 10 years. In the 20 years since their discovery, a great deal has been learned about their localization and cellular functions. Both PCs share the same four domains: the propeptides perform important roles in controlling activation and targeting; the catalytic domains confer specificity, with PC1/3 possessing a more restricted binding pocket than that of PC2; the P domain is required for expression and contributes to enzymatic properties; and the C-terminal tail assists in proper routing to granules. PC1/3, but not PC2, exists in full-length and C-terminally truncated forms that exhibit different biochemical properties. Both enzymes associate with binding proteins; proSAAS is thought to modulate precursor cleavage by PC1/3, while co-expression of 7B2 is obligatory for the formation of active PC2. Finally, new studies have revealed an increasingly important role for PC1/3 polymorphisms and mutations in glucose homeostasis and obesity.

Book Description
Proteins are considered supremely important for the organization, survival, and functioning of living organisms. They were considered stable and static molecules until the early 1940s, when RudolphSchoenheimer demonstrated that proteins exist in a constant dynamic process of synthesis and degradation (proteostasis), absolutely essential for life. Since then, general and limited protein degradation became some of the most fascinating aspects of biological sciences. This book is focused on a particular aspect of protein degradation, namely, limited proteolysis, which gives rise to bioactive peptides as a result of the enzymatic action of proteinases and peptidases, which are enzymes that hydrolyze specific peptide bonds of proteins and peptides, respectively. In a broad sense, bioactive peptides are any fragment of endogenous or exogenous proteins able to elicit either physiological or pathological activities. Here, we aim at presenting to the readers that bioactive peptides are not merely produced through random processes during protein degradation, but rather through a well-organized enzymatic process that is deeply integrated in the homeostatic processes of living organisms.

Book Description
Side Reactions in Peptide Synthesis, based on the author’s academic and industrial experience, and backed by a thorough review of the current literature, provides analysis of, and proposes solutions to, the most frequently encountered side reactions during peptide and peptidomimetic synthesis. This valuable handbook is ideal for research and process chemists working with peptide synthesis in diverse settings across academic, biotech, and pharmaceutical research and development. While peptide chemistry is increasingly prevalent, common side reactions and their causes are often poorly understood or anticipated, causing unnecessary waste of materials and delay. Each chapter discusses common side reactions through detailed chemical equations, proposed mechanisms (if any), theoretical background, and finally, a variety of possible solutions to avoid or alleviate the specified side reaction. Provides a systematic examination on how to troubleshoot and minimize the most frequent side reactions in peptide synthesis Gives chemists the background information and the practical tools they need to successfully troubleshoot and improve results Includes optimization-oriented analysis of side reactions in peptide synthesis for improved industrial process development in peptidyl API (active pharmaceutical ingredient) production Answers the growing, global need for improved, replicable processes to avoid impurities and maintain the integrity of the end product. Presents a thorough discussion of critical factors in peptide synthesis which are often neglected or underestimated by chemists Covers solid phase and solution phase methodologies, and provides abundant references for further exploration
