Book Description
Ion Transport in Prokaryotes provides an advance treatise on ion transport and prokaryotic organisms. This book is divided into three main topics—cation transport systems, anion transport systems, and plasmid-encoded transport systems. This compilation specifically discusses the proton transport and proton-motive force in prokaryotic cells, potassium transport in bacteria, and bioenergetic functions of sodium ions. The calcium transport in prokaryotes, phosphate transport in prokaryotes, and transport of organic acids in prokaryotes are also elaborated. This text likewise covers the chloride, nitrate, and sulfate transport in bacteria and bacterial magnesium, manganese, and zinc transport. This publication is recommended for biologists, specialists, and students interested in the bacterial ion transport system.

Book Description
1.1. Definition of Terms-Thrombosis, Thromboembolic Disease, Atherosclerosis, and Blood Clotting The terms heart attack or myocardial infarction are more commonly used than thrombosis. The infarct-muscle destruction is simply the end result and thrombosis is the real cause of the heart attack. Thrombosis may be defined as the process of formation of a coalescent or agglutinated solid mass of blood components in the blood stream. Thrombi formed in either arteries or veins often cause occlusion in the vascular system and prevent blood flow. Obstruc to the blood vessel usually occurs at the site where the thrombi deposit. tion Furthermore, thrombi may break loose, travel through the circulating blood stream, and cause obstruction at some distal point of narrowing elsewhere. The mass or thrombus that moves is referred to as an "embolus." The two phenomena are lumped together under the term thromboembolic disease. Thrombosis that reduces blood supply to the heart is the primary factor in heart attacks.

Book Description
This volume is based on the proceedings of an International Symposium on "Cytochrome Systems: Molecular Biology and Bioenergetics" that was held at Selva di Fasano near Bari, Italy, between April 7 and 11,1987. It contains papers covering the subjects discussed at the Symposium, contributed both by participants of the meeting and by some invited speakers who were not able to attend. The aim of the Symposium was to bring together experts in various rese arch strategies currently being applied to the study of cytochrome systems, including molecular genetics, protein chemistry, enzymology of electron transfer and protonmotive activity in energy-transducing biological mem branes. Because of the high degree of complexity of cytochrome systems and the increasing sophistication in recent years of the different experimen tal approaches, there has been a growing specialization - sometimes even a tendency to "over-specialization" - among scientists working in this field. This in itself seemed to justify a meeting where representatives of various disciplines could exchange their results and discuss their conclusions. In addition, and perhaps even more importantly, it was felt that meetings of this kind provide an opportunity for a "cross-fertilization" of approaches and ideas among representatives of various fields of science. The present meeting proved to be an ample illustration of the success of such an inter action.

Book Description
Structure and Function of Membrane Proteins documents the proceedings of the International Symposium on Structure and Function of Membrane Proteins held in Selva di Fasano on May 23-26, 1983. This compilation makes it possible to obtain more information on the structure of membrane proteins, determining the structure in order to understand the function, and mechanism of action that is only understood by knowledge of the atomic structure. The gathering of data on the function of membrane proteins prior to knowledge of their structure is valuable for characterizing and defining the proteins. Once the structure is known, another stage of research will penetrate to the functional assignments of the structure. Other topics covered include the physical methods for the structure-function relationship; identification and mapping of sites in membrane proteins; and primary structure of transport proteins. Tertiary structure and molecular shape of membrane proteins and structure-function relationship in membrane proteins are also examined. This book is a good source of information for students and individuals conducting research on biochemistry, specifically on membrane proteins.

Book Description
A preface should justify the existence of the book it precedes and this is invariably done in scientific texts by reference to the explosive growth of the field since the last such volume appeared. In molecular biology, most fields can be justifiably described as growing explosively, as should be the case for a young and vigorous science, but the study of membrane proteins stands out as one which has taken giant strides in the last few years. Ignorance of the structure and function of membrane proteins at the molecular level was certainly not due to lack of interest but rather was a result of lack of appropriate techniques. It has above all been the development of new experimental methods which has wrenched membrane biochemistry out of what Anthony Martonosi fetchingly called its 'romantic phase' (Le. lots of ideas and few facts), into an era when the determination of membrane protein structure and mechanism is a reasonable goal. Membrane proteins are generally classified as peripheral or integral. Peripheral proteins are relatively easily dissociated from membranes by mild treatments whence their study is essentially no different to that of soluble proteins. This book therefore concentrates on integral proteins which are strongly bound to the membrane by hydrophobic interactions with lipids. A crucial step in their study is of necessity the d~velopment of methods of solubilization and purification under non-denaturing conditions.

Book Description
Current Topics in Bioenergetics, Volume 13 presents the biophysical and biochemical approaches that are valuable in some systems and that may be readily be applied to others. This book discusses the function and structure relationship of energy-transducing membranes that has played an essential role in the progress and development in the field of bioenergetics. Organized into six chapters, this volume begins with an overview of the bioenergetics processes that require a molecular description of the structure and reaction mechanisms of the individual energy-transducing catalysts. This text then provides an understanding to the methodology for initiation of an electron paramagnetic resonance (EPR) investigation in this field of research. This book discusses as well the developments in spin label EPR techniques. The final chapter deals with immunological techniques that are used for studying the biochemistry and molecular biology of membrane proteins. This book is a valuable resource for physiologists, biologists, and biochemists.

Book Description
Current Topics in Cellular Regulation: Volume 28 is a collection of papers that deals with enzyme-enzyme interactions, regulation of metabolic reaction pathways, the relevance of intracellular amino acid pool in the regulation of protein metabolism, and the production of superoxide by phagocytic leukocytes. Other papers discuss the regulation of adrenergic receptor function by phosphyrylation, a membrane-bound metallo-endopeptidase (meprin), as well as the covalent modification as a mechanism of marking proteins for degradation. One paper notes that the transfer pathway involving enzyme-enzyme recognition is associated with molecular specificity features over those demanded by the molecular structural constraints of the individual enzyme sites. The Albery and Knowles principle, under certain conditions, shows that intermediary metabolites within a particular pathway exist in states of nearly equal free energy. One paper describes that the amino acid pool size and content are governed by the conditioning of intracellular proteins and the metabolic activity of the cell. The paper also suggests that intracellular pools do not regulate protein metabolism. The collection can prove beneficial for biochemists, micro-biologists, cellular researchers, and academicians involved in the study of cellular biology or physiology.
