As a new feature, each chapter now contains intriguing openended questions highlighting “What We Don’t Know,” introducing students to challenging areas of future research. Updated end-of-chapter problems reflect new research discussed in the text, and these problems have been expanded to all chapters by adding questions on developmental biology, tissues and stem cells, pathogens, and the immune system.

How Enzymes Work

Author: Haruo Suzuki
Publisher: CRC Press
ISBN: 9789814463935
Release Date: 2015-02-05
Genre: Medical

For a long time, enzymes have been studied by measuring their activity, which has led to the advancement of "enzyme kinetics." In recent years, the mechanism of enzyme reaction has been explained in detail on the basis of the 3D structure. Genetic engineering and the 3D structural analysis of enzymes contribute to these advancements in enzymology. This book starts with an introduction to various enzymes to show how interesting enzymes are, which is followed by historical kinetic studies on enzymes and the overall and rapid-reaction kinetics. The subsequent topics describe the basics of protein structure, the control of enzyme activity, and the purification of enzymes. A case on the kinetic and structural studies of l-phenylalanine oxidase is also presented. There are many good books on enzyme kinetics, but few describe their kinetic and structural aspects. This book deals with both and contains many references that can be good sources for further reading. It is handy and is especially helpful for beginners. A number of figures, including some with stereo expression, facilitate observing the 3D structure of enzymes.

Structure Function Relationships of Proteolytic Enzymes

Author: P. Desnuelle
Publisher: Elsevier
ISBN: 9781483261171
Release Date: 2014-05-10
Genre: Science

Structure–Function Relationships of Proteolytic Enzymes provides information pertinent to the fundamental aspects of proteolytic enzymes. This book presents the historical role of proteolytic enzyme as a group in protein and enzyme chemistry. Organized into 23 chapters, this book begins with an overview of the results obtained from investigation on the chymotrypsinogens of porcine origin. This text then examines the differences of amino acid sequence between chymotrypsin, trypsin, and elastase that affect the substrate binding site, which reflect the specificity differences between these enzymes. Other chapters consider the kinetic parameters related to the trypsin-catalyzed hydrolysis of several model peptides. This book discusses as well the acetylation of trypsin, which result in functional consequences varying from complete inactivation to promotion of activity. The final chapter deals with the physical properties of stem bromelain in comparison with the data for three other sulfhydryl proteases of plant origin. This book is a valuable resource for enzymologists, microbiologists, and biochemists.

It also describes the use of carbon-13-labeled lipids, as indicators of molecular mobility. It explains the lipid-protein interactions involving two integral membrane proteins, mitochondrial cytochrome oxidase and calcium-dependent ATPase of muscle sarcoplasmic reticulum. The book goes on to present NMR studies on the organization and conformation of phospholipids, chloroplast membranes, and erythrocyte membranes. It also presents the ESR study of spectrin-phospholipid associations. It discusses the use of fluorescence probes, electrokinetics, neutron diffraction and ion theory studies of phospholipid-protein association, hormone disease, and senescence effects on prokaryotic and eukaryotic cells. Moreover, this book presents the experiments and phosphorus-31 NMR methodology to simultaneously monitor the intracellular pH and phosphate metabolism in a beating heart, functioning kidney, or an intact living microorganism. This book then describes physical probing of intracellular fluidity and structural changes attending tissue or cell cycles. It also relates relatively narrow lines in the hydrogen-1 NMR spectrum of the extremely viscous complex of the muscle protein troponin and highly polymerized tropomyosin. Structure-function studies of fibrous proteins, such as collagen, actin, and myosin, and active site analysis of enzymes are also presented.

The Enzymes of Biological Membranes

Author: A.N. Martonosi
Publisher: Springer Science & Business Media
ISBN: 9781468445985
Release Date: 2012-12-06
Genre: Science

In the first edition of The Enzymes of Biological Membranes, published in four volumes in 1976, we collected the mass of widely scattered information on membrane-linked enzymes and metabolic processes up to about 1975. This was a period of transition from the romantic phase of membrane biochemistry, preoccupied with conceptual developments and the general properties of membranes, to an era of mounting interest in the specific properties of membrane-linked enzymes analyzed from the viewpoints of modem enzymology. The level of sophistication in various areas of membrane research varied widely; the structures of cytochrome c and cytochrome b5 were known to atomic detail, while the majority of membrane-linked enzymes had not even been isolated. In the intervening eight years our knowledge of membrane-linked enzymes ex panded beyond the wildest expectations. The purpose of the second edition of The Enzymes of Biological Membranes is to record these developments. The first volume describes the physical and chemical techniques used in the analysis of the structure and dynamics of biological membranes. In the second volume the enzymes and met abolic systems that participate in the biosynthesis of cell and membrane components are discussed. The third and fourth volumes review recent developments in active transport, oxidative phosphorylation and photosynthesis.

Gene Families

Publisher: World Scientific
ISBN: 9789814492607
Release Date: 2001-06-22
Genre: Medical

This archival volume is an invaluable collection of rigorously reviewed articles by experts in the fields of gene families, DNA, RNA and proteins, to commemorate the passing of a giant of science — Professor Clement L Markert (1917–1999). In 1959, Clement Markert and Freddy Moller developed the concept of the isozyme, which paved the way for extensive studies of enzyme, protein and gene multiplicity across all living organisms. This important scientific discovery has had a profound influence on the biological sciences for more than 40 years, and has provided the basis for regular international meetings to discuss the biological and biomedical implications of enzyme multiplicity. More recently, this concept has been extended to a wide range of gene families of DNA, RNA, proteins and enzymes.

Publisher: John Wiley & Sons
ISBN: 9781118742815
Release Date: 2013-11-08
Genre: Computers

New insights into the evolution and nature of proteins Exploring several distinct approaches, this book describes the methods for comparing protein sequences and protein structures in order to identify homologous relationships and classify proteins and protein domains into evolutionary families. Readers will discover the common features as well as the key philosophical differences underlying the major protein classification systems, including Pfam, Panther, SCOP, and CATH. Moreover, they'll discover how these systems can be used to understand the evolution of protein families as well as understand and predict the degree to which structural and functional information are shared between relatives in a protein family. Edited and authored by leading international experts, Protein Families offers new insights into protein families that are important to medical research as well as protein families that help us understand biological systems and key biological processes such as cell signaling and the immune response. The book is divided into three sections: Section I: Concepts Underlying Protein Family Classification reviews the major strategies for identifying homologous proteins and classifying them into families. Section II: In-Depth Reviews of Protein Families focuses on some fascinating super protein families for which we have substantial amounts of sequence, structural and functional data, making it possible to trace the emergence of functionally diverse relatives. Section III: Review of Protein Families in Important Biological Systems examines protein families associated with a particular biological theme, such as the cytoskeleton. All chapters are extensively illustrated, including depictions of evolutionary relationships. References at the end of each chapter guide readers to original research papers and reviews in the field. Covering protein family classification systems alongside detailed descriptions of select protein families, this book offers biochemists, molecular biologists, protein scientists, structural biologists, and bioinformaticians new insight into the evolution and nature of proteins.
