Book Synopsis Differential Ion Mobility Spectrometry by : Alexandre A. Shvartsburg
Download or read book Differential Ion Mobility Spectrometry written by Alexandre A. Shvartsburg and published by CRC Press. This book was released on 2008-12-24 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the last decade, scientific and engineering interests have been shifting from conventional ion mobility spectrometry (IMS) to field asymmetric waveform ion mobility spectrometry (FAIMS). Differential Ion Mobility Spectrometry: Nonlinear Ion Transport and Fundamentals of FAIMS explores this new analytical technology that separates and characterizes ions by the difference between their mobility in gases at high and low electric fields. It also covers the novel topics of higher-order differential IMS and IMS with alignment of dipole direction. The book relates the fundamentals of FAIMS and other nonlinear IMS methods to the physics of gas-phase ion transport. It begins with the basics of ion diffusion and mobility in gases, covering the main attributes of conventional IMS that are relevant to all IMS approaches. Building on this foundation, the author reviews diverse high-field transport phenomena that underlie differential IMS. He discusses the conceptual implementation and first-principles optimization of FAIMS as a filtering technique, emphasizing the dependence of FAIMS performance metrics on instrumental parameters and properties of ion species. He also explores ion reactions in FAIMS caused by field heating and the effects of inhomogeneous electric field in curved FAIMS gaps. Written by an accomplished scientist in the field, this state-of-the-art book supplies the foundation to understand the new technology of nonlinear IMS methods.
Book Synopsis Native Mass Spectrometry and Complementary Techniques to Characterize Biological Macromolecular Assemblies by : Andrew S. Norris
Download or read book Native Mass Spectrometry and Complementary Techniques to Characterize Biological Macromolecular Assemblies written by Andrew S. Norris and published by . This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The structures adopted by biological macromolecules and macromolecular complexes are directly tied to their function. By better understanding the relationship between structure and function of biomolecules, lifesaving and life-changing interventions can be designed such as small molecule inhibitors of viral enzymes. Characterization of macromolecules with high-resolution structural techniques has greatly improved our fundamental understanding of how structures dictate function. High-resolution structural techniques including x-ray crystallography, cryo-electron microscopy, and nuclear magnetic resonance spectroscopy, however, have many challenges and so they require complementary techniques. Native mass spectrometry is one such technique that can be used to interrogate macromolecular assemblies and accurately determine molecular weight(s), oligomeric state(s), ligand-binding, and topology of the assembly. Native mass spectrometry has the advantage of not being limited by some of the common issues encountered by high-resolution techniques like molecular flexibility and sample heterogeneity that can limit resolution attainable or prevent structure determination altogether. This attribute is particularly valuable for the characterization of protein-nucleic acid complexes that have proven to be some of the more challenging complexes for high-resolution techniques. Throughout this work, native mass spectrometry is emphasized as a clear approach for examining differences in macromolecular assemblies that highlight the structural diversity of macromolecular systems which would otherwise not be evident. Chapter 3 describes identification of the physiological protein interface of a plant protein, BX1.This approach demonstrates the use of native mass spectrometry and covalent cross-linking mass spectrometry to solve a common issue with X-ray crystallography, namely artificial protein contacts formed during the crystallization process. Chapter 4 describes the investigation of the assembly pathway for RNase P, a multi-subunit archaeal ribonucleoprotein. Additionally, native mass spectrometry addresses the absence of a protein subunit in the cryo-EM structure of the same RNase P. Chapter 5 describes the investigation of the different assembly states of DNA annealing proteins. A cryo-EM reconstruction of a section of one of the protein-DNA complexes was determined. For this protein, native mass spectrometry complemented the cryo-EM study by determining the composition of the entire complex. With the native mass spectrometry assembly data for DNA annealing proteins and the cryo-EM for one of these proteins, proposed revisions to the current model of single-strand annealing are presented. Finally, in Chapter 6, cooperative ligand binding of three cyclic homo-oligomers is reported and a cooperative binding model, the nearest-neighbor model, was used to fit the data to quantitively determine thermodynamic parameters. RNA binding was also tested, but work is still ongoing. Overall, the work presented herein demonstrates the use of native mass spectrometry to study the assembly states of macromolecular complexes and hereby gain insights not easily accessible by other structural techniques.

Book Synopsis Structural Analysis of Macromolecular Complexes Using Electrospray Ionization Mass Spectrometry Based Approaches by : Jingshu Guo
Download or read book Structural Analysis of Macromolecular Complexes Using Electrospray Ionization Mass Spectrometry Based Approaches written by Jingshu Guo and published by . This book was released on 2013 with total page 405 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mass spectrometry (MS) has become one of the most robust, reliable and widely used analytical techniques in scientific research due to factors like its speed of analysis, ease of operation, high sensitivity, and applicability to a broad range of analytes. The development of the so-called "soft" ionization methods electrospray ionization (ESI) and matrix-assisted laser desorption/ionization (MALDI) played a pivotal role in the application of MS to biochemical and biophysical fields enabling comprehensive studies of biomolecules, macromolecules and their complexes. This dissertation presents method development and the application of MS-based strategies for complete sequence and structure determination of hemoglobin (Hb); investigation of the interaction between human Hb and Band 3; characterization of the interaction between Alanyl-tRNA synthetase with tRNA and various ligands; and characterization of various thiol-protected silver nanoclusters. First, the complete primary amino acid sequences of hemoglobin from the endangered species snow leopard (Uncia uncia), Amur tiger (Panthera tigris altaica), Cheetah (Acinonyx jubatus) and Francois' Langur (Trachypithecus francoisi) were determined using a combination of the bottom-up approach to proteomics in combination with single crystal X-ray diffraction. In this approach, MS was used to provide on average 70% coverage of the sequences, which was used in refinement of the diffraction data. The electron density maps from the diffraction data were used to determine the parts of the sequences not covered by MS as well as differentiate between isomeric residues. During the refinement of the X-ray diffraction data, a unique conformational state, the Bform, for naturally occurring ligated hemoglobin was discovered in two feline Hbs. Structural comparisons and possible biological relevance for the B-form will be presented. The binding of human hemoglobin to synthetic peptides corresponding to the Hb-binding sites of human erythrocyte Band 3 is also presented. The effects on binding of ligation and oxidation state of normal human HbA; human sickle HbS; Hb-binding site and peptide length; and Band 3 N-terminal acetylation were investigated. The optimization of MS instrumental parameters and solution conditions for stabilizing and protecting labile thiol-protected silver nanoclusters through ionization, mass analysis and detection is presented. The relatively much more stable and well characterized gold-glutathione cluster Au25(SG)18 was used as a model for instrumental optimization (SG, glutathione). The most crucial instrumental parameters to protecting the clusters were cone gas flow rate, trap/transfer collision energy, and source temperature. Using these optimized parameters and adjustment of solution conditions led to the formula assignment for Ag32(SG)19, the species isolated from band 6 of a polyacrylamide gel electrophoretic separation. Using a similar approach the formula assignment for Ag44L30-4 (L, p-mercaptobenzoic acid) was confirmed. Collision induced dissociation (CID) studies were used to demonstrate that Ag43L28-3, another abundant species in the mass spectra was in fact a fragment of the intact cluster from the facile loss of AgL2-. CID and ion mobility mass spectrometry (IMMS) of Au25(SG)18, Ag32(SG)19, and Ag44L30-4 were used to gain insight into the surface structure and stability of the fragile silver clusters. Finally, the 3'-tRNA binding site on E. coli Alanyl-tRNA synthetase was identified by first crosslinking the 3'-periodate-oxidized tRNAala to the enzyme followed by the bottom-up MS sequencing. Modified lysine residues identified were 74, 526 585, 637, 739 and 648. Lys 74 was in the aminoacylation domain while 526 585, 637, 739 and 648 were in the editing domain. These results highlight an alteration of the 3'-terminal of tRNAala interaction with the enzyme. To study the stability ARS with various ligands, non-hydrolysable adenylate analogs, ASAd and GSAd, were used. Data shows that complete binding of ASAd and GSAd was achieved and that binding occurred in a 1:1 stoichiometry. Binding of ASAd, the analog of the cognate ligand, stabilizes the enzyme against changes in solution pH relative to the apo-enzyme and the enzyme with GSAd bound.
