This book was released on 2015 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: Membrane proteins perform a variety of functions within our cells. They transport nutrients and waste across the lipid barrier, transmit signals from one part of the body to another, and run our immune system. However, despite their ubiquitous and vital presence in all organisms, relatively little is known about this class of proteins compared to their soluble counterparts. In this work I have set out to use deep UV resonance Raman (DUVRR) spectroscopy to characterize structural and environmental transitions of proteins and applied the results to studies involving intramembrane proteases and their substrates. DUVRR has been used extensively to observe protein secondary structure. This work contains the results of three main studies I have conducted during my graduate career. In the first I show results from the first experiment to look simultaneously at both secondary and tertiary structure as a protein transitions from a molten globule to ordered state. In the second study tracks the structural and environmental changes of a small peptide as it transitions from a soluble, disordered state through two membrane-bound, structurally ordered states. I was then able to apply the findings of these experiments to study intramembrane proteolysis, wherein I describe substrate characteristics and their interactions with proteases.

This book was released on 2017 with total page 109 pages. Available in PDF, EPUB and Kindle. Book excerpt: Membrane protein function and structure determination is vital for pharmaceutical development and disease prevention. Despite the various methods of protein structure elucidation in use, a need still exists for techniques that are of adequate resolution, rapid, inexpensive, and compatible with the membrane environment of these proteins. Deep UV resonance Raman (dUVRR) spectroscopy is an emerging structurally sensitive spectroscopic technique for analyzing membrane protein structure. The backbone amide modes are resonance enhanced in dUVRR spectra while the membrane's lipid features are not, resulting in strong membrane protein spectral features in near native environments. In order to better define dUVRR spectral features of membrane proteins, a series of model helical peptides, poly(LA)7, were designed. By substituting select residues of the transmembrane region of poly(LA)7, the propensity of helical structure within a membrane has also been studied. Using these model membrane peptides in increasingly dehydrated environments (aqueous, surfactant, and bilayer), hydration depended changes in the spectra are characterized.

Download or read book Protein Structure Function Relationships in Foods written by Rickey Y. Yada and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: Food proteins constitute a diverse and complex collection of biological macro molecules. Although contributing to the nutritional quality of the foods we con sume, proteins also act as integral components by virtue of their diverse functional properties. The expression of these functional properties during the preparation, processing and storage of foods is largely dictated by changes to the structure or structure-related properties of the proteins involved. Therefore, germane to the optimal use of existing and future food protein sources is a thorough understanding of the nature of the relationships between structure and function. It is the goal of this book to aid in better defining these relationships. Two distinct sections are apparent: firstly, those chapters which address struc ture-function relationships using a variety of food systems as examples to demonstrate the intricacies of this relationship, and secondly, those chapters which discuss techniques used to either examine structural parameters or aid in establishing quantitative relationships between protein structure and function. The editors would like to thank all contributors for their assistance, co-operation and, above all, their patience in putting this volume together, and the following companies/organizations for their financial support without which it would not have been the success it was: Ault Foods Limited, Best Foods Canada Limited, Natural Sciences and Engineering Research Council of Canada, Ontario Ministry of Agriculture and Food, Quest International Canada Inc., and University of Guelph.

Download or read book Ultraviolet Spectroscopy of Proteins written by Alexander P. Demchenko and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 323 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this book is to give a comprehensive description of the basic methods used in the ultraviolet spectroscopy of proteins, to discuss new trends and development of these methods, and to analyze their different applications in the study of various aspects of protein structure and dynamics. Ultraviolet spectroscopy is one of the oldest and most popular methods in the field of biochemistry and molecular biophysics. At present, it is difficult to imagine the biochemical laboratory without a recording spectrophotometer or spectrofluorimeter. There are several hundreds of publications directly devoted to protein ultraviolet spectroscopy and in a great number of studies UV spectroscopic methods are used for the structural analysis of different proteins. Meanwhile a unified description of the theoretical basis of the methods, experimental techniques, data analysis, and generalization of results obtained in solving the specific problems of protein structure are lacking. There are three reasons for which a monograph on ultraviolet spectroscopy is needed today. Firstly, there has been significant growth in facilities of experimental technique, its precision, and versatility associated with computer data analysts. This new technique is available to a wide circle of scientists engaged in the field of protein research. Most of them are not spectroscopists and, thus, there is a need for a conceivable and precise source of information on how to use this method and what kind of data it should provide.

Download or read book Protein Structure written by Robert Austin and published by Springer. This book was released on 2014-11-14 with total page 515 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is concerned with the physical aspects of molecular and electronic tunneling in biological systems, and the extent to which protein structure controls these events. The scope is very broad and this volume could almost be a textbook in biophysics. Both fundamental processes and the extrapolation to physiological events are stressed. The discussion sections are remarkably frank and offer insight into the basic problems confronting physists and chemists as they seek to apply their techniques to biological systems. This book on the physics of biomolecules reflects recent progress in understanding the biological function of the key protein molecules from detailed knowledge of their physics. New and exciting are the glasslike aspects of protein structures and the discussion of proteins as fractals. Other topics dealt with are low-temperature kinetics and reactivity, structure and charge exchange, and charge separation in photosynthetic reaction centers.

This book was released on 2010 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation focuses on the folding dynamics of a bacterial membrane protein, Outer Membrane Protein A (OmpA), using fluorescence and Ultraviolet resonance Raman spectroscopy. Our model [Beta]-barrel membrane protein, OmpA, contains five native anchoring Tryptophan residues. The spectroscopic properties of trp residues are highly sensitive to the local environment, making it an ideal probe for membrane protein folding studies. Utilizing trp fluorescence, refolding studies were performed on single trp mutants of OmpA to determine the thermodynamic stability of these trp mutants. The important noncovalent interactions that promote stability in OmpA are pairwise aromatic interactions and hydrogen bonds with the N1H moiety of trp. Refolding studies were also performed on truncated single-trp mutants, in which the soluble domain of the protein was removed. These studies resulted in increased stability relative to the full-length protein and suggest the absence of the soluble domain may destabilize the unfolded transmembrane domain. Ultraviolet resonance Raman spectroscopy (UVRR) is a powerful vibrational technique that can selectively probe different biological chromophores depending on excitation wavelength. Excitation wavelength dependence studies were performed on OmpA using wavelengths from 206.5 nm - 236.5 nm. This study determined an optimal excitation wavelength of 228-nm to selectively enhance signal from trp residues in OmpA. Additionally, UVRR was used to monitor changes in trp environmental hydrophobicity, hydrogen bonding, and dihedral torsion angle in different conformations of OmpA. The first UVRR spectra were collected of OmpA in a highly scattering environment and show differences in folded and unfolded conformations of the protein, showing the applicability of this technique to study membrane protein folding. UVRR spectra were collected of trp mutants of OmpA at different time points in the folding/insertion process to determine the types of noncovalent interactions with trp residues, and the folding timescales these interactions occur. Our results indicate noncovalent interactions start to form within the first 20 minutes after initiation of folding into DMPC vesicles and continue to show subtle changes over the course of the folding process. Additionally, there is evidence for interactions between trp residues and lipids, inter-residue hydrogen bonding, and amino-aromatic interactions.
