Download Biochemical Applications of Raman and Resonance Raman Spectroscopes Book in PDF, ePub and Kindle
Biochemical Applications of Raman and Resonance Raman Spectroscopies focuses on the application of Raman and resonance Raman spectroscopies to biochemical problems. The book reviews biological systems and details the application of Raman spectroscopy to biological molecules such as proteins, nucleic acids, and lipids. It also looks at codevelopments of lasers, optics, and electronics that drive advances in experimental Raman spectroscopy, along with the important ramifications of these advances for biochemical applications. This volume is organized into eight chapters and begins with an overview of the theoretical and experimental aspects of Raman spectroscopy, including a very brief explanation of what Raman and resonance Raman spectroscopies are and a discussion of their advantages and disadvantages for biochemical studies. The explanation of the Raman and resonance Raman effects is taken up in more detail in the next chapter, which develops the concept of the vibrational motions of molecules by initially considering mechanical ""ball and spring"" models and goes on to use this concept to formulate a classical model for Raman scattering. The resonance Raman effect is then described by another model which emphasizes the discrete or quantized energy levels available to a molecule. The reader is also introduced to the experimental aspects of Raman spectroscopy and the application of Raman spectroscopy across the entire field of biochemistry. Each chapter contains an outline of the basic chemistry and biochemical nomenclature involved. This book will be of interest to chemists, biochemists, and spectroscopists, as well as graduate students and experienced research workers.

One effective approach for exploring structure/function relationships in heme proteins is to study proteins that have been reconstituted with modified hemes so as to systematically perturb the protein-heme interface. However, some reconstituted heme proteins may contain substantial fractions of a "non native" state in which the orientation of the heme in the folded pocket differs from the native conformation by a 180° rotation about the [alph alpha - gamma gamma] meso axis. In fact, this "non native" state has also been shown to exist in some native proteins, including several mammalian globins. In order to define changes in the active site structure associated with this "disorder", we have applied resonance Raman spectroscopy to the metMb derivatives, using selectively deuterated protohemes to associate the observed modes with specific fragments of the heme. Resonance Raman spectroscopy is also employed to characterize heme site structural changes arising from conformational heterogeneity in deoxyMb and ligated derivatives; i.e., the ferrous CO (MbCO) and ferric cyanide (MbCN) complexes. Interestingly, while substantial changes in the disposition of the peripheral vinyl and propionate groups can be inferred from the dramatic spectral shifts, the bonds to the internal histidyl imidazole ligand and those of the Fe-CO and Fe-CN fragments are not significantly affected by the heme rotation, as judged by lack of significant shifts in the [upsilon](Fe-NHis), [upsilon](Fe-C) and [upsilon](C-O) modes. We have synthesized protohemes with selectively labeled vinyl groups and have effectively reconstituted them into apo-myoglobin in order to assign the so-called "vinyl bending" modes of heme group in native and reversed forms of myoglobin to their specific molecular fragments based on their isotopic shift with these vinyl labeled protohemes. In a separate project, these vinyl labeled hemes have been employed to further define structural changes in cytochrome P450cam upon substrate binding. Substrate binding to cytochrome P450cam is known to induce the distortions of the out of plane modes such as [gamma gamma]6 and [gamma gamma]7 modes as well as the heme peripheral substituents. The detection of these low frequency modes is especially important as the disposition of these groups can modify the heme reduction potential.

Download Vibrational Spectroscopy in Life Science Book in PDF, ePub and Kindle
The authors describe basic theoretical concepts of vibrational spectroscopy, address instrumental aspects and experimental procedures, and discuss experimental and theoretical methods for interpreting vibrational spectra. It is shown how vibrational spectroscopy provides information on general aspects of proteins, such as structure, dynamics, and protein folding. In addition, the authors use selected examples to demonstrate the application of Raman and IR spectroscopy to specific biological systems, such as metalloproteins, and photoreceptors. Throughout, references to extensive mathematical and physical aspects, involved biochemical features, and aspects of molecular biology are set in boxes for easier reading. Ideal for undergraduate as well as graduate students of biology, biochemistry, chemistry, and physics looking for a compact introduction to this field.

The membrane protein Cytochrome c Oxidase (CcO) is one of the most important functional bio-molecules. It appears in almost every eukaryotic cell and many bacteria. Although the different species differ in the number of subunits, the functional differences are merely marginal. CcO is the terminal link in the electron transfer pathway of the mitochondrial respiratory chain. Electrons transferred to the catalytic center of the enzyme conduce to the reduction of molecular oxygen to water. Oxygen reduction is coupled to the pumping of protons into the inter-membrane space and hence generates a difference in electrochemical potential of protons across the inner mitochondrial membrane. This potential difference drives the synthesis of adenosine triphosphate (ATP), which is the universal energy carrier within all biological cells. rnrnThe goal of the present work is to contribute to a better understanding of the functional mechanism of CcO by using time-resolved surface enhanced resonance Raman spectroscopy (TR-SERRS). Despite intensive research effort within the last decades, the functional mechanism of CcO is still subject to controversial discussions. It was the primary goal of this dissertation to initiate electron transfer to the redox centers CuA, heme a, heme a3 and CuB electrochemically and to observe the corresponding redox transitions in-situ with a focus on the two heme structures by using SERRS. A measuring cell was developed, which allowed combination of electrochemical excitation with Raman spectroscopy for the purpose of performing the accordant measurements. Cytochrome c was used as a benchmark system to test the new measuring cell and to prove the feasibility of appropriate Raman measurements. In contrast to CcO the heme protein cc contains only a single heme structure. Nevertheless, characteristic Raman bands of the hemes can be observed for both proteins.rnrnIn order to investigate CcO it was immobilized on top of a silver substrate and embedded into an.
