Book Description
In recent years, there have been considerable developments in techniques for the investigation and utilisation of enzymes. With the assistance of a co-author, this popular student textbook has been updated to include techniques such as membrane chromatography, aqueous phase partitioning, engineering recombinant proteins for purification and due to the rapid advances in bioinformatics/proteomics, a discussion of the analysis of complex protein mixtures by 2D-electrophoresis and RPHPLC prior to sequencing by mass spectroscopy. Written with the student firmly in mind, no previous knowledge of biochemistry, and little of chemistry, is assumed. It is intended to provide an introduction to enzymology, and a balanced account of all the various theoretical and applied aspects of the subject which are likely to be included in a course. - Provides an introduction to enzymology and a balanced account of the theoretical and applied aspects of the subject - Discusses techniques such as membrane chromatography, aqueous phase partitioning and engineering recombinant proteins for purification - Includes a discussion of the analysis of complex protein mixtures by 2D-electrophoresis and RPHPLC prior to sequencing by mass spectroscopy

Book Description
Directed evolution comprises two distinct steps that are typically applied in an iterative fashion: (1) generating molecular diversity and (2) finding among the ensemble of mutant sequences those proteins that perform the desired fu- tion according to the specified criteria. In many ways, the second step is the most challenging. No matter how cleverly designed or diverse the starting library, without an effective screening strategy the ability to isolate useful clones is severely diminished. The best screens are (1) high throughput, to increase the likelihood that useful clones will be found; (2) sufficiently sen- tive (i. e. , good signal to noise) to allow the isolation of lower activity clones early in evolution; (3) sufficiently reproducible to allow one to find small improvements; (4) robust, which means that the signal afforded by active clones is not dependent on difficult-to-control environmental variables; and, most importantly, (5) sensitive to the desired function. Regarding this last point, almost anyone who has attempted a directed evolution experiment has learned firsthand the truth of the dictum “you get what you screen for. ” The protocols in Directed Enzyme Evolution describe a series of detailed p- cedures of proven utility for directed evolution purposes. The volume begins with several selection strategies for enzyme evolution and continues with assay methods that can be used to screen enzyme libraries. Genetic selections offer the advantage that functional proteins can be isolated from very large libraries s- ply by growing a population of cells under selective conditions.

Book Description
Fundamentals of Enzyme Kinetics details the rate of reactions catalyzed by different enzymes and the effects of varying the conditions on them. The book includes the basic principles of chemical kinetics, especially the order of a reaction and its rate constraints. The text also gives an introduction to enzyme kinetics - the idea of an enzyme-substrate complex; the Michaelis-Menten equation; the steady state treatment; and the validity of its assumption. Practical considerations, the derivation of steady-state rate equations, inhibitors and activators, and two-substrate reactions are also explained. Problems after the end of each chapter have also been added, as well as their solutions at the end of the book, to test the readers' learning. The text is highly recommended for undergraduate students in biochemistry who wish to study about enzymes or focus completely on enzymology, as most of the mathematics used in this book, which have been explained in detail to remove most barriers of understanding, is elementary.

Book Description
Mitochondria are sometimes called the powerhouses of eukaryotic cells, because mitochondria are the site of ATP synthesis in the cell. ATP is the universal energy currency, it provides the power that runs all other life processes. Humans need oxygen to survive because of ATP synthesis in mitochondria. The sugars from our diet are converted to carbon dioxide in mitochondria in a process that requires oxygen. Just like a fire needs oxygen to burn, our mitochondria need oxygen to make ATP. From textbooks and popular literature one can easily get the impression that all mitochondria require oxygen. But that is not the case. There are many groups of organismsm known that make ATP in mitochondria without the help of oxygen. They have preserved biochemical relicts from the early evolution of eukaryotic cells, which took place during times in Earth history when there was hardly any oxygen avaiable, certainly not enough to breathe. How the anaerobic forms of mitochondria work, in which organisms they occur, and how the eukaryotic anaerobes that possess them fit into the larger picture of rising atmospheric oxygen during Earth history are the topic of this book.

Book Description
There is no doubt that nowadays, biology benefits greatly from mathematics. In particular, cellular biology is, besides population dynamics, a field where tech niques of mathematical modeling are widely used. This is reflected by the large number of journal articles and congress proceedings published every year on the dynamics of complex cellular processes. This applies, among others, to metabolic control analysis, where the number of articles on theoretical fundamentals and experimental applications has increased for about 15 years. Surprisingly, mono graphs and textbooks dealing with the modeling of metabolic systems are still exceptionally rare. We think that now time is ripe to fill this gap. This monograph covers various aspects of the mathematical description of enzymatic systems, such as stoichiometric analysis, enzyme kinetics, dynamical simulation, metabolic control analysis, and evolutionary optimization. We believe that, at present, these are the main approaches by which metabolic systems can be analyzed in mathematical terms. Although stoichiometric analysis and enzyme kinetics are classical fields tracing back to the beginning of our century, there are intriguing recent developments such as detection of elementary biochemical syn thesis routes and rate laws for the situation of metabolic channeling, which we have considered worth being included. Evolutionary optimization of metabolic systems is a rather new field with promising prospects. Its goal is to elucidate the structure and functions of these systems from an evolutionary viewpoint.

Book Description
Biomarkers of Inborn Errors in Metabolism: Clinical Aspects and Laboratory Determination is structured around the new reality that laboratory testing and biomarkers are an integral part in the diagnosis and treatment of inherited metabolic diseases. The book covers currently used biomarkers as well as markers that are in development. Because biomarkers used in the initial diagnosis of disease may be different than the follow-up markers, the book also covers biomarkers used in both the prognosis and treatment of inherited metabolic disorders. With the introduction of expanded new-born screening for inborn metabolic diseases, an increasing numbers of laboratories are involved in follow-up confirmatory testing. The book provides guidance on laboratory test selection and interpreting results in patients with suspected inherited metabolic diseases. The book provides comprehensive guidance on patient diagnosis and follow-up through its illustrative material on metabolic pathways, genetics and pathogenesis, treatment and prognosis of inherited metabolic diseases, along with essential information on clinical presentation. Each chapter is organized with a uniform, easy-to-follow format: a brief description of the disorder and pathway; a description of treatment; biomarkers for diagnosis; biomarkers followed for treatment efficacy; biomarkers followed for disease progression; confounding conditions that can either: affect biomarker expression or mimic IEMs; other biomarkers: less established, future. - Provides comprehensive information on the tests/biomarkers selection in newborn screening and follow-up of newborn screens - Categorizes biomarkers into diagnostic markers, disease follow-up markers, and prognostic biomarkers - Covers confounding factors that can alter biomarkers in the absence of inborn errors of metabolism - Offers guidance on how to distinguish acquired causes from inborn errors of metabolism
