This book was released on 2006-08-05 with total page 455 pages. Available in PDF, EPUB and Kindle. Book excerpt: ‘‘Biopolymers’’ are polymeric materials of biological origin, including globular, membrane, and fibrous proteins, polypeptides, nucleic acids, po- saccharides, lipids, etc. and their assembly, although preference to respe- ive subjects may be different among readers who are more interested in their biological significance or industrial and/or medical applications. Nevert- less, characterizing or revealing their secondary structure and dynamics may be an equally very important and useful issue for both kinds of readers. Special interest in revealing the 3D structure of globular proteins, nucleic acids, and peptides was aroused in relation to the currently active Structural Biology. X-ray crystallography and multidimensional solution NMR sp- troscopy have proved to be the standard and indispensable means for this purpose. There remain, however, several limitations to this end, if one intends to expand its scope further. This is because these approaches are not always straightforward to characterize fibrous or membrane proteins owing to extreme difficulty in crystallization in the former, and insufficient spectral resolution due to sparing solubility or increased effective molecular mass in the presence of surrounding lipid bilayers in the latter.

This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Membrane proteins help control nearly every process in the cell, which is why approximately 50% of pharmaceuticals currently on the market target membrane proteins. Knowledge of structure-function relationships of these proteins could be leveraged to produce more efficient drugs. However, the traits that make membrane proteins so interesting also make them difficult targets for traditional structure elucidation techniques. X-ray crystallography relies on the use of single crystals, production of which are elusive for membrane proteins due to their inherent dynamic loops and stretches of hydrophobic residues, which contribute to aggregation and/or loss of function without the presence of a lipid environment. Solution NMR experiences difficulty dealing with slow molecular tumbling due to the large sizes of membrane proteins. Conversely, solid-state NMR (SSNMR) has no inherent size limitation and does not require the use of crystals, which presents SSNMR with the unique capability to study membrane proteins in native environments at atomic-resolution. However, this technique is still a relatively new tool for solving structures of biomolecules. Here, we begin to develop strategies for solid-state NMR de novo structure determination. We provide a 0́−divide-and-conquer0́+ investigation of an E. coli 41 kDa membrane protein complex, DsbA/DsbB. We begin by completing chemical shift assignments, the first step in structure determination in NMR studies, of the 21 kDa protein DsbA to optimize sensitivity and resolution of data collection and analysis of large systems. We then use this study to drive forward structural examination of the disulfide bond forming system DsbA/DsbB. Finally, SSNMR techniques are used to study a 144 kDa cytochrome bo3 ubiquinol oxidase demonstrating the power of this technique to investigate large membrane complexes in native environments.

Available in PDF, EPUB and Kindle. Book excerpt: The complexity and heterogeneity of biological systems has posed an immense challenge in recent years. An increasingly important tool for obtaining molecular and atomic scale information on a range of large biological molecules and cellular components is solid-state NMR. This technique can address fascinating problems in structural biology, including the arrangement of supramolecular complexes and fibril formation in relation to molecular folding, misfolding and aggregation. Advances in Biological Solid-State NMR brings the reader up to date with chapters from international leaders of this growing field, covering the most recent developments in the methodology and applications of solid-state NMR to studies of membrane interactions and molecular motions. A much needed discussion of membrane systems is detailed alongside important developments in in situ analysis. Topics include applications to biological membranes, membrane active peptides, membrane proteins, protein assemblies and in-cell NMR. This exposition of an invaluable technique will interest those working in a range of related spectroscopic and biological fields. A basic introduction invites those interested to familiarise themselves with the basic mathematical and conceptual foundations of solid-state NMR. A thorough and comprehensive discussion of this promising technique follows, which is essential reading for those working or studying at postgraduate level in this exciting field.

This book was released on 2010-08-06 with total page 482 pages. Available in PDF, EPUB and Kindle. Book excerpt: Membrane proteins, representing nearly 40% of all proteins, are key components of cells involved in many cellular processes, yet only a small number of their structures have been determined. Membrane Protein Structure Determination: Methods and Protocols presents many detailed techniques for membrane protein structure determination used today by bringing together contributions from top experts in the field. Divided into five convenient sections, the book covers various strategies to purify membrane proteins, approaches to get three dimensional crystals and solve the structure by x-ray diffraction, possibilities to gain structural information for a membrane protein using electron microscopy observations, recent advances in nuclear magnetic resonance (NMR), and molecular modelling strategies that can be used either to get membrane protein structures or to move from atomic structure to a dynamic understanding of a molecular functioning mechanism. Written in the highly successful Methods in Molecular BiologyTM series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Comprehensive and easy to use, Membrane Protein Structure Determination: Methods and Protocols serves as an ideal reference for scientists seeking to further our knowledge of these vital and versatile proteins as well as our overall understanding of the complicated world of cell biology.

This book was released on 2004 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: Solid-state NMR is a powerful tool in the structure and dynamic studies of biological systems. In this thesis, novel techniques are developed for this purpose and various advanced solid-state NMR techniques are used to investigate the structure-function relationships of fibrous and membrane proteins. The chemical shift tensor serves as a sensitive probe of protein conformation. Techniques that combine dipolar modulation with CSA recoupling to determine the CSA tensor orientation under magic-angle spinning are developed. The C[alpha] CAS tensor of model helical and sheet peptides with known crystal structures are determined. The experimental results agree well with ab initio calculations. We use solid-state NMR to understand the structural basis of elastin function. Our hydration dynamics studies on an 81 kDa elastin-mimetic protein show that this protein is much more mobile at 30% hydration level compared to most other globular proteins. This high mobility contributes to the entropy of the system and facilitates the entropy-driven elasticity of elastin. Our high-resolution structural characterization of an elastin-mimetic peptide shows that the protein adopts two types of structures: about 35% of molecules exhibit compact turn structures and approximately 65% of molecules extended [beta]-strand structures. Conformational equilibrium between the two states may facilitate elastin extension and relaxation. Colicin Ia is a toxin that forms ion channels in the inner membrane of the target cell. To understand colicin channel function, we have carried out resonance assignment and dynamic studies on the 21 kDa channel domain of colicin Ia. A spectral editing technique that selects the more structurally informative non-bonded 1H-13C correlations in the 2D H-C HETCOR spectrum is developed and applied to colicin to obtain the 1H chemical shift assignment. Residue type assignments of 13C and 15N are obtained by various 2D correlation experiments under MAS. The topology and dynamics of membrane bound colicin under different ionic strengths and membrane surface charge densities are investigated by 1H spin diffusion and 2D isotropic-anisotropic correlation experiments. Our results show that the optimal channel activity of colicin requires a certain degree of segmental rigidity of the protein.
