Book Synopsis Synthetic Combinatorial Peptide Libraries and Their Application in Decoding Biological Interactions by : Michael Cameron Sweeney
Download or read book Synthetic Combinatorial Peptide Libraries and Their Application in Decoding Biological Interactions written by Michael Cameron Sweeney and published by . This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: The synthesis of peptides was revolutionized by the adoption of solid-phase synthetic techniques. Subsequent improvement, evolution, and refinement of this chemical technique has allowed research into areas of biology not previously accessible with such speed and breadth. Because of the efficiency and flexibility of the chemistry involved in peptide synthesis, libraries representing millions of unique natural, modified, or unnatural peptides can be constructed rapidly and in high enough purity as to obviate the need for purification. In this work, libraries were synthesized for screening against individual protein domains in an effort to both determine the preferred peptidyl binding partner types for each, as well as to establish an optimized, broadly applicable methodology for screening other domains. One of the problems encountered during the development of the screening methodology was the low success-rate of sequence determination for the peptides selected by each domain. Herein we report the successful modification of the peptide ladder mass spectrometry sequencing technique referred to as partial Edman degradation (PED). Success-rates were improved to greater than 90% for full-length sequencing determination of peptide up to 8-mers, even for more difficult phosphotyrosine (pY)-containing peptides. As a result of this improvement, three pY-binding Src Homology 2 (SH2) domains and two N-terminus binding Baculoviral Inhibitor-of-Apoptosis Repeat (BIR) domains were screened against their respective libraries and the preferred ligand types for each was determined. The advantage of sequencing by the PED method became especially clear in the case of the N-terminal SH2 (N-SH2) domain of Src Homology 2 Protien Tyrosine Phosphatase 2 (SHP-2) as previously unidentified sub-classes of binding consensus motifs were distinguishable due to the discreet nature of the sequencing technique. This work demonstrates the usefulness and potential generality of peptide library screening by this method.

This book was released on 2013-01-07 with total page 27 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research Paper (undergraduate) from the year 2012 in the subject Chemistry - Bio-chemistry, grade: "-", , language: English, abstract: Extracellular alpha amylase was produced from Aspergillus oryzae under solid state fermentation. House hold agro-wastes were used as medium which were considered as one of the major pollutants due to unfavorable gas production via natural fermentation beside creating disposal problem. Investigations were carried out to evaluate the effect of various carbohydrate sources e.g. glucose, maltose, lactose, sucrose and soluble starch with different concentrations on the production of fungal alpha amylase utilizing agricultural wastes as the fermentation medium. Studies were also carried out to evaluate the effect of various heat stable amino acids e.g. glycine, histidine, proline, leucine and isoleucine with different concentrations on the production of fungal alpha amylase utilizing agricultural wastes as the fermentation medium. The results indicated that maximum activity of alpha amylase (6639.85 U/gds) was obtained at 0.5% concentration of sucrose solution with a r2 of 0.9692 when compared to control (3319.95 U/gds) and other carbohydrates used. Maximum activity of alpha amylase (10407.80 U/gds) was also obtained at 0.75% concentration of proline solution with an r2 of 0.6816 when compared to control (3035.60 U/gds) and other amino acids used in our present study.
Book Synopsis Fungal Siderophores by : Kalyani Dhusia
Download or read book Fungal Siderophores written by Kalyani Dhusia and published by Springer Nature. This book was released on 2021-02-08 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past few decades, it has been realized through research that fungal siderophores epitomize the uptake of iron as well as other essential elements like zinc, magnesium, copper, nickel and arsenic. Understanding the chemical structures of different fungal siderophores and the membrane receptors involved in uptake of mineral ions has opened new areas for research. In this edited volume, recent research is presented on fungal siderophores in one comprehensive volume to provide researchers a strong base for future research. Siderophores are the low molecular weight, high affinity iron-chelating compounds produced by bacteria and fungi. They are responsible for transporting iron across the cell membrane. Fungi produce a range of hydroxamate siderophores involved in the uptake of essential elements in almost all microorganisms and plants. In recent years, siderophores have been used in molecular imaging applications to visualize and understand cellular functions, which thus provide an opportunity to identify new drug targets. Therefore, knowledge of fungal siderophores has become vital in current research. Siderophores have received much attention in recent years because of their potential roles and applications in various research areas. Their significance in these applications is because siderophores have the ability to bind a variety of metals in addition to iron, and they have a wide range of chemical structures and specific properties. For instance, siderophores function as biocontrols, biosensors, and bioremediation and chelation agents, in addition to their important role in weathering soil minerals and enhancing plant growth. This book focuses on siderophores with the following significant points. It discusses leading, state-of-the-art research in all possible areas on fungal siderophores. The contributors are well-known and recognized authorities in the field of fungal siderophores. It discusses a projection of practical applications of fungal siderophores in various domains. This is the first book exclusively on fungal siderophores. In this comprehensive, edited volume, we show leading research on fungal siderophores and provide the most recent knowledge of researchers' work on siderophores. This book presents in-depth knowledge on siderophores to researchers working in areas of health sciences, microbiology, plant sciences, biotechnology, and bioinformatics.

Download or read book Comprehensive Chirality written by and published by Newnes. This book was released on 2012-12-31 with total page 5635 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although many books exist on the subject of chiral chemistry, they only briefly cover chiral synthesis and analysis as a minor part of a larger work, to date there are none that pull together the background information and latest advances in one comprehensive reference work. Comprehensive Chirality provides a complete overview of the field, and includes chiral research relevant to synthesis, analytic chemistry, catalysis, and pharmaceuticals. The individual chapters in each of the 9 volumes provide an in depth review and collection of references on definition, technology, applications and a guide/links to the related literature. Whether in an Academic or Corporate setting, these chapters will form an invaluable resource for advanced students/researchers new to an area and those who need further background or answers to a particular problem, particularly in the development of drugs. Chirality research today is a central theme in chemistry and biology and is growing in importance across a number of disciplinary boundaries. These studies do not always share a unique identifying factor or subject themselves to clear and concise definitions. This work unites the different areas of research and allows anyone working or researching in chiral chemistry to navigate through the most essential concepts with ease, saving them time and vastly improving their understanding. The field of chirality counts several journals that are directly and indirectly concerned with the field. There is no reference work that encompasses the entire field and unites the different areas of research through deep foundational reviews. Comprehensive Chirality fills this vacuum, and can be considered the definitive work. It will help users apply context to the diverse journal literature offering and aid them in identifying areas for further research and/or for solving problems. Chief Editors, Hisashi Yamamoto (University of Chicago) and Erick Carreira (ETH Zürich) have assembled an impressive, world-class team of Volume Editors and Contributing Authors. Each chapter has been painstakingly reviewed and checked for consistent high quality. The result is an authoritative overview which ties the literature together and provides the user with a reliable background information and citation resource.
