Computational and theoretical tools for understanding biological processes at the molecular level is an exciting and innovative area of science. Using these methods to study the structure, dynamics and reactivity of biomacromolecules in solution, computational chemistry is becoming an essential tool, complementing the more traditional methods for structure and reactivity determination. Modelling Molecular Structure and Reactivity in Biological Systems covers three main areas in computational chemistry; structure (conformational and electronic), reactivity and design. Initial sections focus on the link between computational and spectroscopic methods in the investigation of electronic structure. The use of Free Energy calculations for the elucidation of reaction mechanisms in enzymatic systems is also discussed. Subsequent sections focus on drug design and the use of database methods to determine ADME (absorption, distribution, metabolism, excretion) properties. This book provides a complete reference on state of the art computational chemistry practised on biological systems. It is ideal for researchers in the field of computational chemistry interested in its application to biological systems.

The series Topics in Current Chemistry presents critical reviews of the present and future trends in modern chemical research. The scope of coverage is all areas of chemical science including the interfaces with related disciplines such as biology, medicine and materials science. The goal of each thematic volume is to give the non-specialist reader, whether in academia or industry, a comprehensive insight into an area where new research is emerging which is of interest to a larger scientific audience. Each review within the volume critically surveys one aspect of that topic and places it within the context of the volume as a whole. The most significant developments of the last 5 to 10 years are presented using selected examples to illustrate the principles discussed. The coverage is not intended to be an exhaustive summary of the field or include large quantities of data, but should rather be conceptual, concentrating on the methodological thinking that will allow the non-specialist reader to understand the information presented. Contributions also offer an outlook on potential future developments in the field. Review articles for the individual volumes are invited by the volume editors. Readership: research chemists at universities or in industry, graduate students.

Biomolecules and Organic Solvents discusses the behavior of enzymes and multi-enzyme complexes in organic solvents, in addition to the problem of water-protein interactions and the characteristics of water at interphases. It attempts to bridge the gap between the all water and the organic solvents systems from the point of view of enzyme structure and function. The mechanism of action of enzymes dispersed in anhydrous organic solvents and the biotechnological perspectives of the field are evaluated, and new information regarding the function and characteristics of complex multi-enzymatic systems and whole cells in organic solvents are examined. New developments regarding the nature of the water pool and interphases of reverse micelles and their enzyme kinetics are also explored. The characteristics and properties of enzymes trapped in reverse micelles are discussed throughout the book. Biomolecules in Organic Solvents is essential reading for biochemists, molecular biologists, and others working in related fields.

Spectroscopy and Modeling of Biomolecular Building Blocks presents an overview of recent advances in the intertwining of the following research fields: photon and electron spectroscopy, quantum chemistry, modelling and mass-spectrometry. The coupling of these disciplines offers a new point of view to the understanding of isolated elementary building blocks of biomolecules and their assemblies. It allows the unambiguous separation between intrinsic properties of biomolecular systems and those induced by the presence of their environment. The first chapters provide background in modelling (I), frequency-resolved spectroscopy using microwave, infrared and UV photons, time-resolved spectroscopy in the femtosecond domain and energy-resolved electron spectroscopy (II) and production of gas-phase neutral and ionic biomolecular species, mass-spectrometry, ion mobility and BIRD techniques (III). Chapter IV is devoted to case studies of gas-phase experimental investigations coupled to quantum or classical calculations. The topics are structural studies of nucleobases and oligonucleotides, peptides and proteins, sugars; neuromolecules; non-covalent complexes; chiral systems, interactions of low-energy electrons with biomolecules in the radiation chemistry context and very large gas-phase biomolecular systems. The fifth chapter concerns the link between gas-phase and liquid-phase. Different treatments of solvation are illustrated through examples pointing out the influence of progressive addition of water molecules upon properties of nucleobases, peptides, sugars and neuromolecules. - Offer a new perspective to the understanding of isolated elementary building blocks of bio molecules - Includes case studies of experimental investigations coupled to quantum or classical calculations

This book describes the basic principles of a novel methodology to investigate the preferential hydration and solvation of proteins in ternary protein-water-organic solvent systems. Protein-water interactions are well-known to play a critical role in determining the function, structure, and stability of protein macromolecules. Elucidation of the processes occurring upon protein hydration in the presence of third component (organic solvents, salts, urea) is essential in a wide range of biophysical, biomedical, and biotechnological applications. In particular, there are many advantages in employing water-poor organic solvents, including the suppression of undesirable side reactions caused by water, the biocatalysis of reversed hydrolytic reactions (transesterification, peptide synthesis), or increased thermostability. Distinct intermediate protein states induced by organic solvents may be responsible for numerous neurodegenerative diseases (Alzheimer's disease, Parkinson's disease, and Huntington's disease). However, the manner in which organic solvents increase/decrease the thermal stability, induce/reduce the extent of denaturation, and stabilize/destabilize the partially folded conformations of proteins (amyloid fibrils and molten globules) is an intricate function of water content in organic liquids. Preferential hydration/solvation is an effective method for revealing the mechanism of the protein stabilization or denaturation. When a protein interacts with a binary water-organic solvent mixture, the three components do not equally mix. Water or organic solvent molecules exist preferentially in the protein's solvation shell. This difference between the solvation shell and bulk solvent in the solvent components has been termed preferential solvation. Preferential solvation is a thermodynamic quantity that describes the protein surface occupancy by the water and cosolvent molecules. This is associated with the actual numbers of water/cosolvent molecules that are in contact with the protein's surface. It was also found that the protein destabilization is directly associated with the preferential binding of the denaturant molecules to specific protein groups.The aim of our study is to monitor the preferential solvation and preferential hydration of the protein macromolecules at low, intermediate, and high water content in organic solvents at 25 oC. Our approach is based on the simultaneous measurements of the absolute values of the water and organic solvent sorption. The preferential solvation/hydration parameters were calculated using the water and organic solvent sorption values. The preferential solvation/hydration parameters were compared with the corresponding changes in the protein structure that transpire regarding the interaction of the protein with organic solvent and water molecules. The effect of organic solvent on the protein structure was investigated by FTIR (Fourier Transform Infrared) spectroscopy.

This book gathers original contributions from a selected group of distinguished researchers that are actively working in the theory and practical applications of solvent effects and chemical reactions. The importance of getting a good understanding of surrounding media effects on chemical reacting system is difficult to overestimate. Applications go from condensed phase chemistry, biochemical reactions in vitro to biological systems in vivo. Catalysis is a phenomenon produced by a particular system interacting with the reacting subsystem. The result may be an increment of the chemical rate or sometimes a decreased one. At the bottom, catalytic sources can be characterized as a special kind of surrounding medium effect. The materials involving in catalysis may range from inorganic components as in zeolites, homogenous components, enzymes, catalytic antibodies, and ceramic materials. . With the enormous progress achieved by computing technology, an increasing number of models and phenomenological approaches are being used to describe the effects of a given surrounding medium on the electronic properties of selected subsystem. A number of quantum chemical methods and programs, currently applied to calculate in vacuum systems, have been supplemented with a variety of model representations. With the increasing number of methodologies applied to this important field, it is becoming more and more difficult for non-specialist to cope with theoretical developments and extended applications. For this and other reasons, it is was deemed timely to produce a book where methodology and applications were analyzed and reviewed by leading experts in the field.
