Lipid-Protein Interactions
This second edition volume expands all chapters of the previous edition, which have been enhanced to cover the most recent developments, the current state of method research, and applications. Additional protocols were added to examine lipid-protein interactions by mass spectrometry, to use protein microarrays to investigate large sets of various proteins, to study membrane protein dynamics by UV resonance Raman spectroscopy, to analyze peptide-induced pore formation in membranes, and to investigate folding and insertion of membrane proteins. Written in the highly successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Cutting-edge and authoritative, Lipid-Protein Interactions: Methods and Protocols, Second Edition is an essential resource for all researchers who are interested in obtaining up-to-date and comprehensive information about membrane structure and function.
Membrane Proteins in Aqueous Solutions
This book is the first to be entirely devoted to the challenging art of handling membrane proteins out of their natural environment, a key process in biological and pharmaceutical research, but one plagued with difficulties and pitfalls. Written by one of the foremost experts in the field, Membrane Proteins in Aqueous Solutions is accessible to any member of a membrane biology laboratory. After presenting the structure, functions, dynamics, synthesis, natural environment and lipid interactions of membrane proteins, the author discusses the principles of extracting them with detergents, the mechanisms of detergent-induced destabilization, countermeasures, and recent progress in developing det...
Protein-Lipid Interactions
In 17 contributions by leading research groups, this first comprehensive handbook in the field covers the interactions between proteins and lipids that make the fabric of biological membranes from every angle. It examines the relevant hermodynamic and structural issues from a basic science perspective, and goes on to discuss biochemical and cell biological processes. The book covers physical principles as well as mechanisms of membrane fusion and fission. Additionally, chapters on bilayer structure and protein-lipid interactions as well as on how proteins shape lipids and vice versa, membrane penetration by toxins, protein sorting, and allosteric regulation of signal transduction across membranes make this a valuable information source for researchers in academia and industry.
β-Strang-Ausbildung eines Faltungsintermediates von BamA
Sascha Herwig beschreibt die Faltung und den Einbau von β-Fass-Membranproteinen am Modell des essenziellen BamA aus Außenmembranen von Escherichia coli, der zentralen Untereinheit des β-Barrel-Assembly-Machinery-Komplexes. Membranproteine des β-Fass-Typs der Außenmembranen von Bakterien oder Zellorganellen werden über diesen Komplex eingebaut. Mit ortsgerichteter Fluoreszenzspektroskopie des β-Strangs 9 der insgesamt 16 β-Stränge umfassenden BamA-Membrandomäne wird in Modellmembranen nachgewiesen, dass der Strang in einem Faltungsintermediat bereits in adsorbierter Form parallel zur Membranoberfläche entsteht.
Einbau und Faltung von β-Fass Membranproteinen in Bakterien
Lisa Gerlach beschäftigt sich mit der Faltung von Membranproteinen – einem komplexen Prozess, der mehrere Faltungsfaktoren erfordert. Sie beschreibt die Funktion des Membran-gebundenen BamB als Faltungshelferprotein für Außenmembranproteine (OMPs) in Gram-negativen Bakterien und seine Bedeutung für den Membranaufbau. Dazu isoliert sie BamB aus Escherichia coli in denaturierter Form. Ausgewählte biochemische und biophysikalische Methoden demonstrieren die Renaturierung von BamB in vorpräparierte Lipid-Modellmembranen und zeigen die Funktion von BamB auf, die Faltung und Insertion des OmpA zu erleichtern.
