Topology of Membrane Proteins

Journal of Chemical Information and Computer Sciences, 2001
Integral membrane proteins play important roles in living cells. Due to difficulties of experimental techniques, theoretical approaches, i.e., topology prediction methods, are important for structure determination of this class of proteins. Here we show a detailed comparison of transmembrane topology prediction methods. According to this comparison, we

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.

Membrane Protein Solubilization

2009
A critical step in any in vitro analysis of membrane proteins is the solubilization of the membrane to extract the protein of interest in an active form to obtain an aqueous solution containing the membrane protein complexed with detergents and lipids in a form suitable for purification and further analysis. This process is particularly delicate as the

Membrane protein complexes

Current Opinion in Structural Biology, 2002
A wide range of membrane protein structures have been published during the past two years. These have included proteins from both eucaryotic and heterologously overexpressed sources. Whereas some of these proteins were crystallised using conventional techniques, others employed the new methods of lipidic cubic phase crystallisation and antibody ...

Proteomics of Membrane Proteins

2003
Publisher Summary The chapter focuses on the proteomics of the membrane proteins. As an increasing number of genomes are sequenced and a growing number of membrane proteins are identified, the gap in knowledge about the structure and function of these proteins is likely to increase. Moreover, in the post-genomic era, with proteomics emerging as a new

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.
