Available in PDF, EPUB and Kindle. Book excerpt: When the last edition of this book was published in 2000, the field of proteomics was in its infancy. At that time, multidimensional liquid chromatographic separations were being introduced as an alternative to traditional gel-based techniques for separating complex protein and peptide mixtures prior to mass spectrometric detection. Today, this approach – referred to as shotgun proteomics – is considered routine for lar- scale global analyses of protein mixtures. Now in its adolescence, proteomics is fundamentally transforming biological and medical research. Much of this transformation can be attributed to technological advancements, particularly in mass spectrometry. Much wider accessibility of hi- resolution and mass measurement accuracy instrumentation in recent years has ini- ated a new revolution in the field by providing more reliable data and shifting the focus from cataloging proteins to precisely quantifying changes in protein abundance over time and in response to stimuli. Advanced mass spectrometers and novel ion d- sociation schemes such as electron transfer/capture dissociation make it possible to venture boldly into the maze of protein posttranslational modifications, which are an integral component of understanding functional proteomics in the spatial and t- poral domains. Another area that has benefited from these advancements is top-down proteomics, an emerging method essential for characterizing various protein variants that has potentially high impact in biomedical research.

This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation presents research focusing on the development of new instrumentation and methodology to leverage ion-ion reactions for proteomic analyses. Electron transfer dissociation (ETD) technologies have proven a valuable alternative to collision-based fragmentation methods for sequencing peptides and proteins to advance global proteome characterization. Chapter 1 outlines the core concepts central to mass spectrometry (MS)-based proteomics, in addition to the basic principles of ETD and various strategies to improve its efficacy - including the technology that is the focus of this work, i.e., activated ion ETD (AI-ETD). Chapter 2 describes the first application of AI-ETD to intact proteins, which are more chemically complex and, thus, more difficult to sequence, than their peptide counterparts. Chapter 3 discusses a new strategy to improve signalto- noise in ETD spectra, which is especially beneficial for intact protein analysis and which has been incorporated into the newest generation of commercially available quadrupole-Orbitrap-linear ion trap hybrid MS systems. AI-ETD capabilities were also recently implemented on this stateof- the-art MS system (Chapter 4), and the ability to perform AI-ETD on this instrument enables comprehensive sequence coverage of moderately-sized intact proteins (Chapter 5), significantly improves proteoform characterization in large-scale analyses of complex mixtures of intact proteins (Chapter 6), and also enhances characterization of larger intact proteins (Chapter 7). Furthermore, AI-ETD improves characterization of post-translational modifications. Chapter 8 demonstrates the utility of AI-ETD for phosphosite localization in phosphopeptides and intact phosphoproteins, and Chapter 9 presents the largest glycoproteomic study to date by using AI-ETD to interrogate intact N-glycopeptides. Beyond positive-mode analyses of peptide and protein cations, ion-ion reactions also bring unique benefits to negative-mode analyses of precursor anions, where collision-based dissociation fails to consistently produce sequence-informative fragments. Chapter 10 describes implementation of negative ETD (NETD) and activated ion NETD (AI-NETD) and their application to whole-proteome sequencing in the negative mode, and Chapter 11 presents a modified search algorithm to improve interpretation of large-scale NETD and AI-NETD data. Conclusions and future directions of these projects are discussed in Chapter 12.

This book was released on 2012 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: Peptides and proteins are integral biomolecules found in all organisms, and are responsible for movement, molecular transport, catalysis, and energy transfer. This dissertation is aimed on the analysis of energy transfer involving fluorescent proteins and development of methodologies for quantitative and imaging analyses of proteins. Such studies are important because energy transfer plays a significant role in numerous chemical, physical, and biological processes, while quantity and location of peptides and proteins are often closely associated with their functions. In the initial study, energy transfer from fluorescent phycobiliproteins to noble metal nanoparticles was analyzed. Solutions of highly fluorescent phycobiliprotein B-phycoerythrin (B-PE) were mixed with colloidal Au and Ag nanoparticles and were characterized by steady-state and time-resolved fluorescence spectroscopy to determine the magnitude and mechanism of the energy transfer. It was found that the protein fluorescence was quenched after the addition of metal nanoparticles. Electron microscopy and absorption spectroscopy confirmed that B-PE was adsorbed onto the nanoparticles, creating a favorable geometry for quenching. Time-resolved fluorescence spectroscopy showed that B-PE fluorescence lifetimes decreased from 2.2 ns to 0.5 and 0.6 ns upon adsorption onto Au and Ag nanoparticles, respectively, corresponding to energy transfer efficiencies of>70%. Our results, which include lifetimes, efficiencies, and energy transfer distances, show that energy was transferred via the surface energy transfer (SET) mechanism, rather than Forster resonance energy transfer (FRET). The results also imply that efficient energy transfer between proteins and metal nanoparticles may be possible regardless of whether or not resonance conditions between emission spectra of the proteins and absorption spectra of nanoparticles are achieved. The second project dealt with quantitative analysis of proteins by a combination of fluorescence spectroscopy and electrospray ionization (ESI) mass spectrometry (MS). While MS is a very sensitive and versatile detection technique, quantification of compounds by MS is challenging due to relatively low reproducibility of ionization. We investigated the native fluorescence of phenylalanine, tryptophan, and tyrosine as a tool that can improve quantification of peptides and proteins by LC-ESI-MS. Natively fluorescent amino acids as well as peptides and proteins containing them were successfully separated by HPLC, and quantified with a spectrofluorimetric detector and a mass spectrometer. Two detectors connected in series enabled sequential measurements of fluorescence intensities and ion signals as well as structural characterization of separated polypeptides. Fluorescence detector provided better linearity and repeatability of quantification than mass spectrometer, and similar sensitivity for most of biomolecules analyzed. The fluorescence signal was linear over 3-4 orders of magnitude with limit of detection in the low picomole or high femtomole range. Hence, spectrofluorimetric detection of native fluorescence can be used as a reliable method that can facilitate quantification of peptides and proteins by LC-ESI-MS. In addition to analyzing native fluorescence of peptides and proteins, the effect of fluorescence dye labeling on ESI efficiency and charging of polypeptides was studied. Peptides and proteins were labeled with fluorescein isothiocyanate (FITC) and separated from the dye by size exclusion chromatography and HPLC. The ESI-MS and LC-ESI-MS analyses of mixtures of labeled and unlabeled polypeptides confirmed that labeling was successful, leading to slight increase in the charging of the most abundant ions in the mass spectra. Further experiments will confirm how derivatization of the peptides and proteins by FITC affects their ionization efficiencies. In the last project, distribution and localization of biomolecules within the mouse tissue sections was studied by matrix-assisted laser desorption/ionization (MALDI)-imaging mass spectrometry (IMS). Peptides and proteins were imaged in brain and spinal cord tissue sections originating from non-transgenic mice and transgenic mice containing the gene for amyotrophic lateral sclerosis (ALS). Tissue sections from apparently healthy and diseased (ALS) mice were coated with sinapinic acid (SA) or a-cyano-4-hydroxycinnamic acid (CHCA) matrixes and imaged using a MALDI-MS instrument. These imaging experiments enabled determination of distribution and localization of peptides and proteins in the spinal cord and brain tissue sections.

Available in PDF, EPUB and Kindle. Book excerpt: Two important biophysical characteristics of proteins, their interaction with ligands and their post-translational modifications, modulate various biological processes including signal transduction, chemical synthesis, and cell function. Protein-ligand interactions include the interactions with protein, peptide, DNA, and metal. Characterization of the physical properties of these interactions (binding interfaces, binding affinities, and the protein conformational changes due to the binding) is essential in understanding the mechanism of related diseases and, more importantly, in future drug design. Mass spectrometry, with its own revolution and improvement, becomes a powerful tool in protein and peptide analysis. In this thesis, we applied two mass spectrometry-based strategies, proteomics and protein footprinting, to characterize these biophysical properties of three disease-related proteins, connexin 43 (Cx43), troponin, and apolipoprotein E (ApoE), and Fenna-Matthews-Olson protein (FMO), which is the key factor in energy transfer of the photosynthetic system of green sulfur bacteria. By the combination of standard proteomics workflow and two fragmentation methods, collision-induced dissociation (CID) and electron transfer dissociation (ETD), we successfully identified 15 serine residues, including one novel site, in the Cx43-CT that are phosphorylated by CaMKII, the activity of which may be important in regulating Cx43 in normal and diseased hearts. We further utilized hydrogen/deuterium exchange (H/DX), one mass spectrometry-based protein footprinting strategy, to examine the binding affinities of troponin C (TnC), a cardiac disease-related protein, with its four metal binding ligands (Ca2+), and their binding order. We then expanded this approach to elucidate the dynamics of TnC within the complex and its interactions with other subunits (TnT and TnI) at peptide-level resolution. This same approach was also applied to two protein-ligand complexes: (1) the interaction of FMO and its binding partner, CsmA baseplate protein, in which the orientation of FMO between chlorosome and membrane can be confirmed, and (2) the interaction of ApoE and Abeta 40, which are both key factors in Alzheimer's disease. Moreover, we improved the spatial resolution of H/DX to residue-level by conducting ETD fragmentation in the study of ApoE oligomerization. Our results reveal, for the first time, the amino acid residues involved in its self-oligomerization. These six applications of mass spectrometry-based approaches show their potential in the characterization of different protein biophysical properties. The investigation of a more complex protein system can then be pursued.

This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The work described in this dissertation involves the development and application of mass spectrometry methods for the analysis of peptides, proteins, and metabolites. Chapter 1 gives a brief overview of the history and fundamentals of bioanalytical mass spectrometry, the utility of electron transfer dissociation (ETD) for the analysis of peptides and proteins, and the use of high resolution gas-chromatography mass spectrometry (GC-MS) to characterize volatile small molecule metabolites from complex mixtures. Chapter 2 explores the role of the reagent cation in negative electron transfer dissociation (NETD) for the analysis of peptide anions. Then Chapter 3 demonstrates the use of activated-ion NETD (AI-NETD) to analyze the negative-mode proteome of yeast. This work proved to generate far greater depth of coverage than previous negative-mode experiments, owing largely to the introduction of IR radiation concurrent to the NETD reaction, which proved to drastically improve peptide identification. For this study, a high pH chromatography method was also developed to greatly improve the ionization of peptide anions using negative electrospray ionization. Chapter 4 characterizes activated-ion ETD (AI-ETD) as a fragmentation method to interrogate proteins with intact disulfide bonds. This method greatly improved the sequence coverage and sequence ion generation compared to other commonly used fragmentation techniques for a set standard proteins. Chapter 5 outlines the creation of a high resolution metabolite mass spectral library using a Q Exactive GC mass spectrometer. This library is then employed to identify metabolites from yeast and human cell cultures, significantly improving the identification confidence over commercially available spectral libraries. Lastly, Chapter 6 describes the multi-omic analysis of yeast strains with a single gene deletion, aiming to correlate genes of known function with genes unknown function.

This book was released on 2011 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: There continue to be great strides in the field of proteomics but as samples become more complex, the ability to increase sequence coverage and confidence in the identification becomes more important. Several methods of derivatization have been developed that can be used in combination with tandem mass spectrometry to identify and characterize proteins. Three types of activation, including infrared multiphoton dissociation, ultraviolet photodissociation, and electron transfer dissociation, are enhanced in this dissertation and compared to the conventional method of collisional induced dissociation (CID) to demonstrate the improved characterization of proteins. A free amine reactive phosphate group was synthesized and used to modify the N-terminus of digested peptides. This phosphate group absorbs at the IR wavelength of 10.6 [mu]m as well as the Vacuum-ultraviolet (VUV) due to an aromatic group allowing modified peptides to be dissociated by infrared multi-photon dissociation (IRMPD) or ultraviolet photodissociation (UVPD) whereas peptides without this chromophore are less responsive to IR or UV irradiation. The PD spectra for these modified peptides yield simplified MS/MS spectra due to the neutralization of all N-terminal product ions from the incorporation the negatively charged phosphate moiety. This is especially advantageous for UVPD due to the great number of product ions produced due to the higher energy deposition of the UV photons. The MS/MS spectra also produce higher sequence coverage in comparison to CID of the modified or unmodified peptides due to more informative fragmentation pathways generated upon PD from secondary dissociation and an increased ion trapping mass range. IRMPD is also implemented for the first time on an orbitrap mass spectrometer to achieve high resolution analysis of IR chromophore-derivatized samples as well as top-down analysis of unmodified proteins. High resolution/high mass accuracy analysis is extremely beneficial for characterization of complex samples due to the likelihood of false positives at lower resolutions/accuracies. For electron transfer dissociation, precursor ions in higher charge states undergo more exothermic electron transfer and thus minimize non-dissociative charge reduction. In this dissertation, cysteine side chains are alkylated with a fixed charge to deliberately increase the charge states of peptides and improve electron transfer dissociation. ETD can also be used to study protein structure by derivatizing the intact structure with a hydrazone reagent. A hydrazone bond will be preferentially cleaved during ETD facilitating the recognition of any modified residues through a distinguishing ETD fragmentation spectrum.

Available in PDF, EPUB and Kindle. Book excerpt: "Protein Structure Analysis - Preparation and Characterization" is a compilation of practical approaches to the structural analysis of proteins and peptides. Here, about 20 authors describe and comment on techniques for sensitive protein purification and analysis. These methods are used worldwide in biochemical and biotechnical research currently being carried out in pharmaceu tical and biomedical laboratories or protein sequencing facilities. The chapters have been written by scientists with extensive ex perience in these fields, and the practical parts are well documen ted so that the reader should be able to easily reproduce the described techniques. The methods compiled in this book were demonstrated in student courses and in the EMBO Practical Course on "Microsequence Analysis of Proteins" held in Berlin September 10-15, 1995. The topics also derived from a FEBS Workshop, held in Halkidiki, Thessaloniki, Greece, in April, 1995. Most of the authors participated in these courses as lecturers and tutors and made these courses extremely lively and successful. Since polypeptides greatly vary depending on their specific structure and function, strategies for their structural analysis must for the most part be adapted to each individual protein. Therefore, advantages and limitations of the experimen tal approaches are discussed here critically, so that the reader becomes familiar with problems that might be encountered.

Chapters 4 to 6 outline advances to the implementation of electron transfer dissociation aimed at increasing the ability to identify protein (Chapter 4) or peptide (Chapters 5 and 6) species. The remainder of this thesis details the application of neutron encoded (NeuCode) mass labels to peptide identification without tandem MS (Chapter 7), top-down quantification of intact proteoforms (Chapter 8), labeling of mammals that enables multiplexed quantitative analysis of mammalian tissue after only 10 days of labeling time (Chapter 9), and targeted quantification of more than 1,000 peptides (Chapter 10). Conclusions and future directions relating to the content of this thesis are discussed in Chapter 11.
