This book was released on 2021-01-20 with total page 520 pages. Available in PDF, EPUB and Kindle. Book excerpt: Disordered proteins are relatively recent newcomers in protein science. They were first described in detail by Wright and Dyson, in their J. Mol. Biol. paper in 1999. First, it was generally thought for more than a decade that disordered proteins or disordered parts of proteins have different amino acid compositions than folded proteins, and various prediction methods were developed based on this principle. These methods were suitable for distinguishing between the disordered (unstructured) and structured proteins known at that time. In addition, they could predict the site where a folded protein binds to the disordered part of a protein, shaping the latter into a well-defined 3D structure. Recently, however, evidence has emerged for a new type of disordered protein family whose members can undergo coupled folding and binding without the involvement of any folded proteins. Instead, they interact with each other, stabilizing their structure via “mutual synergistic folding” and, surprisingly, they exhibit the same residue composition as the folded protein. Increasingly more examples have been found where disordered proteins interact with non-protein macromolecules, adding to the already large variety of protein–protein interactions. There is also a very new phenomenon when proteins are involved in phase separation, which can represent a weak but functionally important macromolecular interaction. These phenomena are presented and discussed in the chapters of this book.

Download or read book Protein Ligand Binding Thermodynamics written by Justin M. Miller and published by American Chemical Society. This book was released on 2023-06-01 with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ligand binding by macromolecules represents a core event of broad relevance to a range of systems, including catalytic systems alongside noncatalytic systems such as nucleic acid binding by transcription factors or extracellular ligand binding by proteins involved in signaling pathways. The scope of this primer is constrained to introduce only foundational models without significant discussion of more advanced topics such as allosteric or linkage effects. Linkage occurs when the binding of a ligand is influenced by the binding of another molecule of the same ligand (homotropic linkage), the binding of a different ligand (heterotropic linkage), physical variables such as temperature or pressure (physical linkage), or changes in macromolecular assembly state (polysteric linkage). Taking this into account, the foundational themes presented in this primer can be used to describe any macromolecule–ligand interaction either by direct use of the models and techniques described here or by applying them to develop more advanced models to explain additional complexities such as those allosteric or linkage effects just mentioned. The target audience of this primer is the senior undergraduate or junior graduate student who lacks a foundation in ligand-binding thermodynamics. As such, we have focused primarily on foundational thermodynamic treatments and presented only general discussions of relevant experimental designs. Readers of this primer will learn how to build a working understanding of common factors that promote energetic favorability for ligand binding; develop a functional toolbox to understand ligand binding from the perspective of collecting, plotting, and interpreting ligand-binding data; enhance proficiency in deriving thermodynamic mechanisms for ligand binding; and become comfortable in interpreting binding data reported in the literature and independently expanding knowledge beyond the scope introduced in this primer.

Download or read book Protein protein Recognition written by Colin Kleanthous and published by Frontiers in Molecular Biology. This book was released on 2000 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of Protein-Protein Recognition is to bring together concepts and systems pertaining to protein-protein interactions in a single unifying volume. In the light of the information from the genome sequencing projects and the increase in structural information it is an opportune time totry to make generalizations about how and why proteins form complexes with each other. The emphasis of the book is on heteromeric complexes (complexes in which each of the components can exist in an unbound state) and will use well-studied model systems to explain the processes of formingcomplexes. After an introductory section on the kinetics, thermodynamics, analysis, and classification of protein-protein interactions, weak, intermediate, and high affinity complexes are dealt with in turn. Weak affinity complexes are represented by electron transfer proteins and integrincomplexes. Anti-lysozyme antibodies, the MHC proteins and their interactions with T-cell receptors, and the protein interactions of eukaryotic signal transduction are the systems used to explain complexes with intermediate affinities. Finally, tight binding complexes are represented by theinteraction of protein inhibitors with serine proteases and by nuclease inhibitor complexes. Throughout the chapters common themes are the technologies which have had the greatest impact, how specificity is determined, how complexes are stabilized, and medical and industrial applications.

Download or read book Protein Reviews written by M. Zouhair Atassi and published by Springer. This book was released on 2017-12-23 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of the Protein Reviews is to serve as a publication vehicle for review articles that focus on crucial current vigorous aspects of protein structure, function, evolution and genetics. The volumes will appear online before they are published in a printed book. Articles are selected according to their importance to the understanding of biological systems, their relevance to the unravelling of issues associated with health and disease or their impact on scientific or technological advances and developments. Volume 19 focusses on Purinergic receptors, also termed purinoceptors. These are plasma membrane proteins present in nearly all mammalian tissues. They participate in a number of cell functions that include proliferation and migration of neural stem cells, vascular reactivity, apoptosis and cytokine secretion and have been associated with learning and memory, feeding conduct, movement and sleep. They facilitate relaxation of smooth muscle of the gut in response to adenosine (P1 receptors) or ATP (P2 receptors). The chapters in this volume are authored by experts in the field. They deal with aspects of structure and biological activity of selected receptor proteins. The first chapter in this volume reviews the current research on the Mechanism of channel gating and regulation of the activity of calcium-activated chloride channel ANO1. This is followed by a chapter dealing with Structure and function of the two-component cytotoxins of Staphylococcus aureus and a chapter on Membrane Fusion and Infection involving the Influenza virus Hemagglutinin. The fourth chapter reviews the impact of arrhythmogenic mutations through the structural determination of the L-type voltage-gated calcium channel. Then there is a chapter that discusses some open questions pertaining to histone post-translational modifications and nucleosome organization in transcriptional regulation. The next chapter deals with regulation of the extracellular SERPINA5 (protein C inhibitor) penetration through cellular membranes. This is followed by a chapter on coding of Class I and II aminoacyl-tRNA synthetases; a chapter on regulation of nephrin phosphorylation in diabetes and chronic kidney injury and a chapter on The Structure-Forming Juncture in oxidative protein folding and the events in the ER. Finally the last chapter deals with the polyspecificity of anti-lipid antibodies and its relevance to the development of autoimmunity.
