Multicellular organisms must be able to adapt to cellular events to
accommodate prevailing conditions. Sensory-response circuits
operate by making use of a phosphorylation control mechanism known
as the "two-component system."
Springer Handbook of Enzymes provides data on enzymes sufficiently well characterized. It offers concise and complete descriptions of some 5,000 enzymes and their application areas. Data sheets are arranged in their EC-Number sequence and the volumes themselves are arranged according to enzyme classes. This new, second edition reflects considerable progress in enzymology: many enzymes are newly classified or reclassified. Each entry is correlated with references and one or more source organisms. New datafields are created: application and engineering (for the properties of enzymes where the sequence has been changed). The total amount of material contained in the Handbook has more than doubled so that the complete second edition consists of 39 volumes as well as a Synonym Index. In addition, starting in 2009, all newly classified enzymes are treated in Supplement Volumes. Springer Handbook of Enzymes is an ideal source of information for researchers in biochemistry, biotechnology, organic and analytical chemistry, and food sciences, as well as for medicinal applications.
This book covers the most recent developments in the analysis of allosteric enzymes and provides a logical introduction to the limits for enzyme function as dictated by the factors that are limits for life. The book presents a complete description of all the mechanisms used for changing enzyme activity. It is extensively illustrated to clarify kinetic and regulatory properties. Eight enzymes are used as model systems after extensive study of their mechanisms. Wherever possible, the human form of the enzyme is used to illustrate the regulatory features.

Enzymes and whole cells are able to catalyze the most complex chemical processes under the most benign experimental and environmental conditions. In this way, enzymes and cells could be excellent catalysts for a much more sustainable chemical industry. However, enzymes and cells also have some limitations for nonbiological applications: fine chemistry, food chemistry, analysis, therapeutics, and so on. Enzymes and cells may be unstable, difficult to handle under nonconventional conditions, poorly selective toward synthetic substrates, and so forth. From this point of view, the transformation-from the laboratory to industry-of chemical processes catalyzed by enzymes and cells may be one of the most complex and exciting goals in biotechnology. For many industrial applications, enzymes and cells have to be immobilized, via very simple and cost-effective protocols, in order to be re-used over very long periods of time. From this point of view, immobilization, simplicity, and stabilization have to be strongly related concepts. Over the last 30 years, a number of protocols for the immobilization of cells and enzymes have been reported in scientific literature. However, only very few protocols are simple and useful enough to greatly improve the functional properties of enzymes and cells, activity, stability, selectivity, and related properties.
Glycosyltransferases (GTs) are essential for the biosynthesis of complex glycoconjugates and are powerful tools to study the functions of complex glycans in health, development and disease. Complex glycoconjugates, such as glycoproteins, proteoglycans and glycolipids, are assembled by GTs which synthesize specific linkages between sugars or sugars and protein. This is in contrast to the non-specific or less specific chemical glycation reactions, transglycosylation and reverse glycosylation reactions. Glycosyltransferases: Methods and Protocols contains a wide range of studies, methods and protocols which form a solid basis for investigations of the role and mechanisms, biology and pathology involving GTs. Written in the successful Methods in Molecular Biology (TM) series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible protocols, and notes on troubleshooting and avoiding known pitfalls. Authoritative and easily accessible, Glycosyltransferases: Methods and Protocols is a vital contribution to glycobiology and glycopathology, and to applications of these enzymes in biotechnology and drug development. It will prove invaluable to students, postdoctoral fellows, and senior scientists carrying on research of GTs that has been intensified over the last years.
Rab GTPases now comprise a family of >63 members. They are
emerging as the key hub element controlling the membrane
architecture of eukaryotic cells. They are intimately involved in
vesicle targeting and fusion in both the endocytic and exocytic
pathways and direct the assembly and disassembly of protein
complexes that include regulators (GEFs and GAPs), effectors
(tethers/motors) and fusion components (SNAREs) that control
membrane targeting and fusion. During the last 3 years the field
has virtually exploded with the identification and characterization
of many new Rab proteins and their effectors.
This volume on conjugation enzymes and transporters serves to bring
together current methods and concepts in an interesting, important
and rapidly developing field of cell and systems biology. It
focuses on the so-called Phase II enzymes of drug metabolism
(xenobiotics), which has important ramifications for endogenous
metabolism and nutrition. Also included are aspects on Phase III,
transport systems. This volume of Methods in Enzymology presents
current knowledge and methodology on glucuronidation, sulfation,
acetylation, and transport systems in this field of research.
Together with the volumes on Quinones and Quinone Enzymes (volumes
378 and 382), and on Glutathione Transferases and gamma-Glutamyl
Transpeptidases (volume 401), the state of knowledge on proteomics
and metabolomics of many pathways of (waste) product elimination,
enzyme protein induction and gene regulation and feedback control
is provided. This volume will help stimulate future investigations
and speed the advance of knowledge in systems biology.
Bioethanol has been recognized as a potential alternative to petroleum-derived transportation fuels. Even if cellulosic biomass is less expensive than corn and sugarcane, the higher costs for its conversion make the near-term price of cellulosic ethanol higher than that of corn ethanol and even more than that of sugarcane ethanol. Conventional process for bioethanol production from lignocellulose includes a chemical/physical pre-treatment of lignocellulose for lignin removal, mostly based on auto hydrolysis and acid hydrolysis, followed by saccharification of the free accessible cellulose portions of the biomass. The highest yields of fermentable sugars from cellulose portion are achieved by means of enzymatic hydrolysis, currently carried out using a mix of cellulases from the fungus Trichoderma reesei. Reduction of (hemi)cellulases production costs is strongly required to increase competitiveness of second generation bioethanol production. The final step is the fermentation of sugars obtained from saccharification, typically performed by the yeast Saccharomyces cerevisiae. The current process is optimized for 6-carbon sugars fermentation, since most of yeasts cannot ferment 5-carbon sugars. Thus, research is aimed at exploring new engineered yeasts abilities to co-ferment 5- and 6-carbon sugars. Among the main routes to advance cellulosic ethanol, consolidate bio-processing, namely direct conversion of biomass into ethanol by a genetically modified microbes, holds tremendous potential to reduce ethanol production costs. Finally, the use of all the components of lignocellulose to produce a large spectra of biobased products is another challenge for further improving competitiveness of second generation bioethanol production, developing a biorefinery.
This work establishes linear-scaling density-functional theory (DFT) as a powerful tool for understanding enzyme catalysis, one that can complement quantum mechanics/molecular mechanics (QM/MM) and molecular dynamics simulations. The thesis reviews benchmark studies demonstrating techniques capable of simulating entire enzymes at the ab initio quantum-mechanical level of accuracy. DFT has transformed the physical sciences by allowing researchers to perform parameter-free quantum-mechanical calculations to predict a broad range of physical and chemical properties of materials. In principle, similar methods could be applied to biological problems. However, even the simplest biological systems contain many thousands of atoms and are characterized by extremely complex configuration spaces associated with a vast number of degrees of freedom. The development of linear-scaling density-functional codes makes biological molecules accessible to quantum-mechanical calculation, but has yet to resolve the complexity of the phase space. Furthermore, these calculations on systems containing up to 2,000 atoms can capture contributions to the energy that are not accounted for in QM/MM methods (for which the Nobel prize in Chemistry was awarded in 2013) and the results presented here reveal profound shortcomings in said methods.
DNA in the nucleus of plant and animal cells is stored in the form of chromatin. Chromatin and the Chromatin remodelling enzymes play an important role in gene transcription.
The aim of this volume is to brief researchers of the importance of
data analysis in enzymology, and of the modern methods that have
developed concomitantly with computer hardware. It is also to
validate researchers' computer programs with real and synthetic
data to ascertain that the results produced are what they expected.
This volume addresses current methods in biological imaging, including extensive sections on MRI, CAT, NMR, PET and other imaging techniques.
The inducible isoforms of the enzymes cyclooxygenase (COX 2), nitric oxide synthase (iNOS) and heme oxygenase 1 (HO-1) have generated great interest as possible therapeutic targets in inflammation. This book is the first publication to address the importance of all three enzymes and the consequences of their interactions to the inflammatory process. The book brings together overviews by leading researchers in the field of the current status of knowledge of COX, NOS and HO in inflammation. These overviews cover a series of new concepts in the mechanism of inflammation. Topics include inducible enzyme involvement in inflammatory processes including the role in vascular permeability, leukocycte migration, granuloma formation, angiogenesis, neuroinflammation and algesia. New findings from transgenic animal models are reviewed. Other chapters address the importance of these enzymes in inflammatory disease states including rheumatoid arthritis, atherosclerosis and multiple sclerosis. The possibility of selective inhibitors or inducers of COX, NOS and HO, and their use in the clinic is discussed. The subject matter of this book is of interest to rheumatologists, pathologists, pharmacologists, neuroscientists and anyone with an academic interest in the mechanisms of inflammation.
Protein phosphatases are a group of enzymes responsible for the
dephosphorylation of various proteins and enzymes in a cell. This
role is an extremely important one since protein phosphorylation
and dephosphorylation is required for the regulation of a large
number of cellular activities.
Liposomes are cellular structures made up of lipid molecules.
Important as a cellular model in the study of basic biology,
liposomes are also used in clinical applications such as drug
delivery and virus studies.
DNA in the nucleus of plant and animal cells is stored in the form
of chromatin. Chromatin and the chromatin remodelling enzymes play
an important role in gene transcription.
This volume focuses on methods related to allosteric enzymes and
receptors, including fluorescent proves, spectroscopic methods and
quantitative analysis as well as on cooperativity in protein
folding. NMR and mass spectrometry methods are discussed.
Quinones are members of a class of aromatic compounds with two
oxygen atoms bonded to the ring as carbonyl groups. This volume
covers more clinical aspects of quinines, such as anticancer
properties, as well as their role in nutrition and in age-related
diseases.

Leading researchers, from the Novartis group that pioneered Gleevec/Gliveca"[ and around the world, comprehensively survey the state of the art in the drug discovery processes (bio- and chemoinformatics, structural biology, profiling, generation of resistance, etc.) aimed at generating PTK inhibitors for the treatment of various diseases, including cancer. Highlights include a discussion of the rationale and the progress made towards generating "selective" low molecular-weight kinase inhibitors; an analysis of the normal function, role in disease, and application of platelet-derived growth factor antagonists; and a summary of the factors involved in successful structure-based drug design. Additional chapters address the advantages and disadvantages of in vivo preclinical models for testing protein kinase inhibitors with antitumor activity and the utility of different methods in the drug discovery and development process for determining "on-target" vs "off-target" effects of kinase inhibitors.
