Protein-Protein Interactions in Membranes

Protein & Peptide Letters, 2011
In this article we review the current status of our understanding of membrane mediated interactions from theory and experiment. Phenomenological mean field and molecular models will be discussed and compared to recent experimental results from dynamical neutron scattering and atomic force microscopy.

Microseparation of membrane proteins [PDF]

Journal of Separation Science, 2009
AbstractMembrane proteins are generally of natural low abundance and insoluble to aqueous solutions. Thus, investigation of membrane proteins is relatively hampered since efficient separation of membrane proteins are rather challenging. Microseparation approaches certainly play an essential role in fulfilling such demanding investigations due to their ...

Spin Labeling of Membranes and Membrane Proteins [PDF]

, 1984
Electron spin resonance (ESR) or electron paramagnetic resonance (EPR) has improved during the last 20 years to a powerful technique to derive structural and dynamic information about membranes and membrane components. The source of an ESR signal is an unpaired electron, which may exist intrinsically in a metalloprotein (e.g., cytochrome c oxidase) or ...

Membrane-protein engineering

Trends in Biotechnology, 1997
Membrane proteins perform many of the essential functions required for life. They are often the targets of medicinal drugs and have many potential uses in biotechnological processes. Therefore our ability to understand them and manipulate their functions is both important and necessary to enable protein engineers to create 'designer' membrane proteins (

Crystallization of membrane proteins

Trends in Biochemical Sciences, 1983
Abstract After a long period of fruitless attempts, three-dimensional crystal of membrane proteins are now available. The best of the crystals are suited for high-resolution structure determination by X-ray crystallography. The use of small detergents and small amphiphilic molecules during crystallization proved to be of great value.

Bioinformatics of Membrane Proteins

2002
As for all proteins, there are three basic problems facing bioinformatics in the field of membrane proteins: to reliably identify membrane proteins in genome-wide data sets, to predict as much as possible about their structure, and to predict as much as possible about their function.

Crystallization of Membrane Proteins

2013
The crystallization of membrane proteins is an essential technique for the determination of atomic models of three-dimensional structures by X-ray crystallography. The compositions of solutions of purified membrane proteins are altered, so as to transiently induce supersaturation, a requirement for crystal nucleation and growth.

Proteins of the synaptic membrane

Neurochemical Research, 1977
The purpose of this communication is to provide a survey of contempory information concerning the composition, disposition, and functional significance of proteins in or on synaptic membranes derived from rat brain synaptosomes. Special emphasis is placed on their content of glycoproteins, fibrous proteins, proteins susceptible to rapid phosphorylation

Structures of membrane proteins

The Journal of Membrane Biology, 1978
The possible conformations of integral membrane proteins are restricted by the nature of their environment. In order to satisfy the requirement of maximum hydrogen bonding, those portions of the polypeptide chain which are in contact with lipid hydrocarbon must be organized into regions of regular secondary structure.
