Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Principles of Protein Structure written by G.E. Schulz and published by Springer Science & Business Media. This book was released on 2013-12-01 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Theory of Phase Transitions in Polypeptides and Proteins written by Alexander V. Yakubovich and published by Springer Science & Business Media. This book was released on 2011-09-01 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are nearly 100 000 different protein sequences encoded in the human genome, each with its own specific fold. Understanding how a newly formed polypeptide sequence finds its way to the correct fold is one of the greatest challenges in the modern structural biology. The aim of this thesis is to provide novel insights into protein folding by considering the problem from the point of view of statistical mechanics. The thesis starts by investigating the fundamental degrees of freedom in polypeptides that are responsible for the conformational transitions. This knowledge is then applied in the statistical mechanics description of helix↔coil transitions in polypeptides. Finally, the theoretical formalism is generalized to the case of proteins in an aqueous environment. The major novelty of this work lies in combining (a) a formalism based on fundamental physical properties of the system and (b) the resulting possibility of describing the folding↔unfolding transitions quantitatively. The clear physical nature of the formalism opens the way to further applications in a large variety of systems and processes.
