Available in PDF, EPUB and Kindle. Book excerpt: Mass spectrometers may be utilized to generate and detect fragmentation patterns of peptides and proteins to acquire mass spectra that allow for accurate amino acid sequence characterization and localization of post-translational modifications. Conventional activation methods utilize collisions with neutral gas molecules to collisionally activate these ions but have some drawbacks, being dependent on charge state and amino acid sequence characteristics. More recent activation methods include radical transfer as well as ultraviolet photodissociation, the latter of which impart higher energy into target ions providing more extensive fragmentation patterns and more sequence information. In the following research all of these activation methods were explored with peptide and protein cations as well as various combinations of such methods to investigate their benefits and limitations. In summary, ultraviolet photodissociation provides the most diverse fragmentation patterns of all researched. Combining radical transfer and subsequent ultraviolet photodissociation termed “hybrid activation” generated interesting effects such as spectral simplification as well as constructive inclusion of fragment ions lacking in ultraviolet photodissociation. Included in this thesis are those interesting findings.

Book excerpt: STRATEGIES FOR PROTEIN AND PEPTIDE CHARACTERIZATION AND QUANTIFICATION USING ELECTRON-TRANSFER DISSOCIATION MASS SPECTROMETRY AND INTRINSIC FLUORESCENCE Jason D. Russell Under the supervision of Associate Professor Joshua J. Coon At the University of Wisconsin-Madison The following chapters detail strategies for peptide and protein sequence analysis featuring electron-transfer dissociation (ETD) tandem mass spectrometry (MS/MS) and quantification using ultraviolet light-induced intrinsic fluorescence (UV-IF). Chapter 1 provides a brief background and overview. Chapter 2 discusses the optimization of the ETD MS/MS duty cycle for large-scale shotgun experiments. In Chapter 3, the first comprehensive analysis of peptide anions using negative ETD (NETD) is detailed. I report in Chapter 4 on the performance of an ion-ion reaction cell for intact protein analysis using large precursor populations for ETD MS/MS. The application of UV-IF for peptide detection and quantification using a custom fluorescence excitation and detection device is discussed in Chapter 5. An analysis of intact proteins from the 26S proteasome of Arabidopsis using top-down mass spectrometry and quantification by UV-IF is described in Chapter 6. In coordination with the Wisconsin Initiative for Science Literacy (WISL), Chapter 7 is a general description of my graduate research intended for non-specialists in an effort to promote science literacy in the broader community.

Available in PDF, EPUB and Kindle. Book excerpt: The Horizon Scientific Press titles focus on high-level microbiology and molecular biology topics. Written by internationally renowned and highly respected leaders in the field, titles in this series comprise of review manuals, practical manuals, and reference texts for research scientists, bioscience professionals and graduate students. Engineering living cells continues to pose immense challenges to the researcher. In fact many bioengineers have only just started to appreciate the full extent of the hierarchical control used by living systems: upon attempts to increase the activity of a "rate-limiting" step, the multiple feedbacks at the metabolic, signaling and genetic levels result in the rate limiting step shifting to elsewhere in that pathway or even to elsewhere in the whole organism. The advent of full-force genomics should enable preventing this response, however, it has been difficult for researchers to know where to turn for guidance. This book aims to help the reader understand and deal with the plasticity of living cell factories and to turn the plasticity into the desired rather than the adverse direction. The book brings together all the recent, most important breakthroughs in this exciting field: Internationally renowned key scientists have reviewed each topic in detail. In the Introduction, the editors give an overview of new approaches and spell out what the engineer and the industry may now really begin to aim for; they even adapt the definition of metabolic engineering to befit the post-genomics era. Other topics included are: the experimental approaches necessary to understand cellular regulation at all of its hierarchical levels, including proteomics [Chapter 2], metabolomics [Chapter 3] and fluxomics [Chapter 4]; new tools that help metabolic engineering [Chapters 5-7]; modeling of living cells, e.g. finding metabolic pathways [Chapter 8] and comparing the actual and predicted use of these in living organisms such as E. coli and Corynebacteria [Chapters 9, 10]; the optimization of cell factories as production organisms (e.g., use of whole cell models, silicon cells, and coordinate manipulation of multiple genes [Chapters 12-15]). A chapter on future perspectives directs further developments of the field in the near future. Metabolic Engineering in the Post Genomic Erais an essential reading for everyone with an interest in engineering living cells including: Metabolic egnineers, bioengineers, biotechnologists, molecular biologists, and pharmaceutical and biotechnology companies.

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 2016-12-14 with total page 525 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume serves as a proteomics reference manual, describing experimental design and execution. The book also shows a large number of examples as to what can be achieved using proteomics techniques. As a relatively young area of scientific research, the breadth and depth of the current state of the art in proteomics might not be obvious to all potential users. There are various books and review articles that cover certain aspects of proteomics but they often lack technical details. Subject specific literature also lacks the broad overviews that are needed to design an experiment in which all steps are compatible and coherent. The objective of this book was to create a proteomics manual to provide scientists who are not experts in the field with an overview of: 1. The types of samples can be analyzed by mass spectrometry for proteomics analysis. 2. Ways to convert biological or ecological samples to analytes ready for mass spectral analysis. 3. Ways to reduce the complexity of the proteome to achieve better coverage of the constituent proteins. 4. How various mass spectrometers work and different ways they can be used for proteomics analysis 5. The various platforms that are available for proteomics data analysis 6. The various applications of proteomics technologies in biological and medical sciences This book should appeal to anyone with an interest in proteomics technologies, proteomics related bioinformatics and proteomics data generation and interpretation. With the broad setup and chapters written by experts in the field, there is information that is valuable for students as well as for researchers who are looking for a hands on introduction into the strengths, weaknesses and opportunities of proteomics.

Book excerpt: The developments in mass spectrometry over the past fifteen years have been impressive in their implications in bioanalytical chemistry. The achievements begin with the inventions of Cf-252 Plasma Desorption Mass Spectrometry by Macfarlane and Fourier Transform Mass Spectrometry by Comisarow and Marshall in the mid 1970s. The former showed the feasibility of producing large gas-phase ions from large biomolecules whereas the latter enhanced the capabilities for ion trapping especially in analytical mass spectrometry. A major achievement was the development by Barber of Fast Atom Bombardment (FAB) mass spectrometry, an advance that heralded a new era in biological mass spectrometry. Contemporary and routine instruments such as magnetic sectors and quadrupoles were rapidly adapted to F AB, and nearly the entire universe of small molecules became amenable to study by mass spectrometry. The introduction of FAB also paved the way for improvement of instrument capability. For example, the upper mass limit of magnet sector mass spectrometers was increased by nearly an order of magnitude by the instrument manufacturers. Furthermore, the technique of tandem mass spectrometry (MS/MS) was given new meaning because important structural information for biomolecules could now be produced for ions introduced by FAB into the tandem instrument. The evolution of MS/MS continues today with the development of ion traps, time-of-flight, and sector instruments equipped with array detection.
