Available in PDF, EPUB and Kindle. Book excerpt: The function of biomacromolecules is controlled by their structure and conformational flexibility. Investigating the structure of biologically important macromolecules can, therefore, yield information that could explain their complex biological function. In addition to X ray crystallography and nuclear magnetic resonance (NMR) methods, pulsed electron paramagnetic resonance (EPR) methods, in particular the pulsed electron electron double resonance (PELDOR) technique has, during the last decade, become a valuable tool for structural determination of macromolecules. Long range distance constraints obtained from pulsed EPR measurements, make it possible to carry out structural refinements on structures from NMR and X ray methods. In addition, EPR yields distance distributions that give information about structural flexibility. The use of EPR for structural studies of biomacromolecules requires in most cases site specific incorporation of paramagnetic centres known as spin labelling. To date, spin labelling nucleic acids has required complex spin labelling chemistry. The first application of a site directed and noncovalent spin labelling method for distance measurements on DNA is described. It is demonstrated that noncovalent spin labelling with a rigid spin label can afford detailed information on internal DNA dynamics using PELDOR. Furthermore, it is shown that noncovalent spin labelling can be used to study DNA protein complexes. PELDOR can also yield information about spin label orientation. Therefore, spin labels with limited flexibility can be used to measure the relative orientation of the spin labelled sites. Although information on orientation can be obtained from 9.7 GHz PELDOR measurements in selected applications, measurements at 97 GHz or higher, increases orientation selection. It is shown that PELDOR measurements on semi rigid and rigid nitroxide biradicals using a home built high power 97 GHz EPR spectrometer (Hiper) and model based simulations yield quantitative information on spin label orientations and dynamics. The most widely used spin labels for EPR studies on biomacromolecules are the aminoxyl (nitroxide) radicals. The major drawbacks of nitroxide spin labels include low sensitivity for distance measurements, fast spin spin relaxation in solution and limited stability in reducing environments. Carbon centered triarylmethyl (trityl) radicals have properties that could eliminate some of the limitations of nitroxide spin labels. To evaluate the use of trityl spin labels for nanometer distance measurements, models systems with trityl and nitroxide spin labels were measured using PELDOR and Double Quantum Coherence (DQC). This study shows that trityl spin labels yield reliable information on interlabel distances and dynamics, establishing the trityl radical as a viable spin label for structural studies on biomacromolecules.

This book was released on 2012-12-06 with total page 454 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume collects a number of the invited lectures and a few selected contrib utions presented at the International Symposium on Structure and Dynamics of Nucleic Acids, Proteins and Membranes held August 31st through September 5th, 1986, in Riva del Garda, Italy. The title of the conference as well as a number of the topics covered represent a continuation of two previous conferences, the first held in 1982 at the University of California in San Diego, and the second in 1984 in Rome at the Accademia dei Lincei. These two earlier conferences have been documented in Structure and Dynamics: Nucleic Acids and Proteins, edited by E. Clementi and R. H. Sarma, Adenine Press, New York, 1983, and Structure and Motion: Membranes, Nucleic Acids and Proteins, edited by E. Clementi, G. Corongiu, M. H. Sarma and R. H. Sarma, Adenine Press, New York, 1985. At this conference in Riva del Garda we were very hesitant to keep the name of the conference the same as the two previous ones. Indeed, a number of topics discussed in this conference were not included in the previous ones and even the emphasis of this gathering is only partly reflected in the conference title. An alternative title would have been Structure and Dynamics of Nucleic Acids, Proteins, and Higher Functions, or, possibly, "higher components" rather than "higher functions.

Book excerpt: This volume looks at the different spectroscopic and biophysical methods used by researchers to study the structure and folding of RNA, and to follow their interactions with proteins. The chapters in this book cover topics such as single-molecule spectroscopy of multiple RNA species; surface plasmon resonance, MS or microcalorimetry for investigating molecular interactions with RNA; FTIR, SAXS, SANS and SRCD spectroscopies to analyze RNA structure; use of fluorescent nucleotides to map RNA-binding sites on proteins surfaces or CryoEM; and much more. Written in the highly successful Methods in Molecular Biology 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. Cutting-edge and comprehensive, RNA Spectroscopy: Methods and Protocols is a valuable resource for anyone interested in learning more about this developing field.
