Available in PDF, EPUB and Kindle. Book excerpt: Explores new applications emerging from our latest understanding of proteins in solution and at interfaces Proteins in solution and at interfaces increasingly serve as the starting point for exciting new applications, from biomimetic materials to nanoparticle patterning. This book surveys the state of the science in the field, offering investigators a current understanding of the characteristics of proteins in solution and at interfaces as well as the techniques used to study these characteristics. Moreover, the authors explore many of the new and emerging applications that have resulted from the most recent studies. Topics include protein and protein aggregate structure; computational and experimental techniques to study protein structure, aggregation, and adsorption; proteins in non-standard conditions; and applications in biotechnology. Proteins in Solution and at Interfaces is divided into two parts: Part One introduces concepts as well as theoretical and experimental techniques that are used to study protein systems, including X-ray crystallography, nuclear magnetic resonance, small angle scattering, and spectroscopic methods Part Two examines current and emerging applications, including nanomaterials, natural fibrous proteins, and biomolecular thermodynamics The book's twenty-three chapters have been contributed by leading experts in the field. These contributions are based on a thorough review of the latest peer-reviewed findings as well as the authors' own research experience. Chapters begin with a discussion of core concepts and then gradually build in complexity, concluding with a forecast of future developments. Readers will not only gain a current understanding of proteins in solution and at interfaces, but also will discover how theoretical and technical developments in the field can be translated into new applications in material design, genetic engineering, personalized medicine, drug delivery, biosensors, and biotechnology.

Download or read book The Effects of Surface Chemistry on the Properties of Proteins Confined in Nano Porous Materials written by and published by . This book was released on 2007 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The entrapment of proteins using the sol-gel route provides a means to retain its native properties and artifi cially reproduce the molecular crowding and confi nement experienced by proteins in the cell allowing investigation of the physico-chemical and structural properties of biomolecules at the biotic/abiotic interface. The biomolecules are spatially separated and 'caged' in the gel structure but solutes can freely permeate the matrix. Thus, properties such as the folding of ensembles of individual molecules can be examined in the absence of aggregation effects that can occur in solution studies. Green fl uorescent protein from Aequorea coerulescens was used as a model protein to examine the unfolding/re-folding properties of protein in silica gels. The recombinant protein was isolated and purifi ed from Escherichia coli extracts by cell lysis, three-phase partitioning, dialysis, and anion exchange chromatography. The purity of the protein was greater than 90% as judged by SDS PAGE gel analysis. Sol-gels were synthesized using tetramethylorthosilicate (TMOS) in combination with, methyltrimethoxyorthosilane (MTMOS), ethyltrimethoxyorthosilane (ETMOS), 3-aminopropyltriethoxysilane (APTES), and 3-glycidoxypropyltrimethoxysilane (GPTMS). The acid induced denaturation and renaturation of GFP was analyzed by UV-visible, fl uorescence, and circular dichroism (CD) spectroscopies. No renaturation was observed in gels that were made with TMOS only, and in the presence of APTES, MTMOS, and ETMOS. However, in gels that were made with GPTMS, the CD and UV-visible spectra indicated that the protein had refolded. The fl uorescence emission spectrum indicated that approximately 20% of fl uorescence had returned. This study highlights the importance of the surface chemistry of the silica gels for the refolding properties of the entrapped GFP. Future studies will investigate the effect of surface chemistry on the thermal and solvent stability of the entrapped protein.

Download or read book Study of the Peptide Peptide and Peptide Protein Interactions and Their Applications in Cell Imaging and Nanoparticle Surface Modification written by Jianpeng Wang and published by Springer. This book was released on 2016-09-26 with total page 103 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis focuses on the study of interactions between protein and peptides and their potential applications in cell imaging and nanoparticle surface modification. Drawing inspiration from naturally occurring coiled-coil binding pairs, it proposes a novel covalent peptide tag and probe system, based on the concept of “affinity guided covalent conjugation.” This newly established methodology provides complementary resolution to protein labeling, imaging and trafficking. By systematically investigating the coordination interaction between protein and quantum dots using various engineered protein ligands, this thesis proposes a general rule for protein self-assembly on the surface of quantum dots and reports a revolutionized nanobelt protein in accordance with this rule. It is an extraordinary example of interdisciplinary research, providing answers to real-life biological problems from a chemistry perspective.

Download or read book Theory of Phase Transitions in Polypeptides and Proteins written by Alexander V. Yakubovich and published by Springer Science & Business Media. This book was released on 2011-09-01 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are nearly 100 000 different protein sequences encoded in the human genome, each with its own specific fold. Understanding how a newly formed polypeptide sequence finds its way to the correct fold is one of the greatest challenges in the modern structural biology. The aim of this thesis is to provide novel insights into protein folding by considering the problem from the point of view of statistical mechanics. The thesis starts by investigating the fundamental degrees of freedom in polypeptides that are responsible for the conformational transitions. This knowledge is then applied in the statistical mechanics description of helix↔coil transitions in polypeptides. Finally, the theoretical formalism is generalized to the case of proteins in an aqueous environment. The major novelty of this work lies in combining (a) a formalism based on fundamental physical properties of the system and (b) the resulting possibility of describing the folding↔unfolding transitions quantitatively. The clear physical nature of the formalism opens the way to further applications in a large variety of systems and processes.
