Details the many benefits of applying mass spectrometry tosupramolecular chemistry Except as a method for the most basic measurements, massspectrometry (MS) has long been considered incompatible withsupramolecular chemistry. Yet, with today's methods, the disconnectbetween these two fields is not warranted. Mass Spectrometry andGas-Phase Chemistry of Non-Covalent Complexes provides aconvincing look at how modern MS techniques offer supramolecularchemists a powerful investigatory toolset. Bringing the two fields together in an interdisciplinary manner,this reference details the many different topics associated withthe study of non-covalent complexes in the gas phase. The textbegins with brief introductions to supramolecular chemistry andsuch relevant mass spectrometric methods as ionization techniques,analyzers, and tandem MS experiments. The coverage continueswith: How the analyte's transition into the gas phase changes covalentbonding How limitations and pitfalls in analytical methods may producedata misinterpretations Artificial supramolecular aggregates and their examination Biomolecules, their complexes, and their examination After the general remarks making up the first section of thebook, the following sections describe specific experimentalprocedures and are illustrated with numerous examples and shorttutorials. Detailed citations end each chapter. Massspectrometrists, supramolecular chemists, students in these fields,and interested readers from other disciplines involving the studyof non-covalent bonds will all value Mass Spectrometry andGas-Phase Chemistry of Non-Covalent Complexes as an innovativeand practical resource.

Spectroscopy and Modeling of Biomolecular Building Blocks

Author: Jean-Pierre Schermann
Publisher: Elsevier
ISBN: 0080558224
Release Date: 2007-10-16
Genre: Science

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

Mass Spectrometry of Nucleosides and Nucleic Acids

Publisher: CRC Press
ISBN: 1420044036
Release Date: 2009-12-21
Genre: Science

Assembling the work of an international panel of researchers, Mass Spectrometry of Nucleosides and Nucleic Acids summarizes and reviews the latest developments in the field and provides a window on the next generation of analysis. Beginning with an overview of recent developments, the book highlights the most popular ionization methods and illustrates the diversity of strategies employed in the characterization and sequencing of DNA and RNA oligomers, nucleosides, nucleotides, and adducts. It describes studies performed on deoxyinosine and its analogues and provides an introduction to tandem mass spectrometry (MS/MS). Next, the contributors examine mass spectrometric application in the study of cyclic nucleotides in biochemical signal transduction. They analyze urinary modified nucleosides and explore DNA adducts. They discuss isotope labeling of DNA-mass spectrometry (ILD-MS) and examine various uses of electrospray ionization mass spectrometry (ESI-MS). The book reviews recent progress in the direct MS characterization of noncovalent nucleic acid-protein complexes, explores the interaction and ionization of guanidine-derived compounds with highly acidic biomolecules, and examines quantitative identification of nucleic acids via signature digestion products detected using mass spectrometry. The book describes a direct-infusion ESI-MS approach that can serve as a screening technique for the presence of modified nucleosides from small RNAs. Lastly, it discusses the LC-MS/MS method for the in vitro replication studies on damage-containing DNA substrates, and concludes with an examination of the influence of metal ions on the structure and reactivity of nucleic acids. The exciting developments in mass spectrometry technology have fueled incredible advances in our understanding of nucleic acids and their complexes. The contributions presented in this volume capture the range of these advances, helping to inspire new findings and avenues of research.

New Methods for the Study of Biomolecular Complexes

Genre: Science

A NATO Advanced Research Workshop entitled New Methods for the Study of Molecular Aggregates was held at Tbe Lodge at Kananaskis Village, Alberta, Canada from 16 -20 June 1996. In fact the meeting was entirely concerned with the problem of analyzing biomolecular complexes, so the title of these proceedings has been altered to give a more precise description of the content. Tbe workshop was hosted by the time-of-flight group of the Department of Physics at the University of Manitoba, and was attended by 64 participants from around the world. '!\venty-one invited talks were given and 27 papers were presented as posters. Of the 48 contributions, 22 papers (12 orals, 10 posters) are included in these proceedings. Tbe subject of the conference was the investigation of noncovalent biomolecular complexes, with particular focus on the application of mass spectrometry to their characterization. '!\vo new ionization techniques introduced in the late 1980s, electrospray ionization (ES I) and matrix-assisted laser desorptionlionization (MALDI), resulted in a breakthrough in mass spectrometry, enabling its use in molecular weight and primary structure determination of biopolymers larger than 100 kDa. Recently it has been discovered that ESI mass spectrometry mayaiso be used to characterize complexes containing noncovalent interactions, thus opening new perspectives for supramolecular chemistry. ESI mass spectrometry has the advantage that the sampie is introduced from a homogenous solution which can be maintained at near physiological conditions of pR, concentration, and temperature.
