Lipid Membranes for Membrane Proteins
2014The molecular dynamics (MD) simulation of membrane proteins requires the setup of an accurate representation of lipid bilayers. This chapter describes the setup of a lipid bilayer system from scratch using generally available tools, starting with a definition of the lipid molecule POPE, generation of a lipid bilayer, energy minimization, MD simulation,

Membrane phosphoinositides and protein–membrane interactions
Amino Acids, 2013Proteins with polybasic clusters bind to negatively charged phosphoinositides at the cell membrane. In this review, I have briefly discussed the types of phosphoinositides naturally found on membrane surfaces and how they recruit protein complexes for carrying out the process of signal transduction.

Journal of the American Chemical Society, 2002
This paper describes the fabrication of microarrays consisting of G protein-coupled receptors (GPCRs) on surfaces coated with gamma-aminopropylsilane (GAPS). Microspots of model membranes on GAPS-coated surfaces were observed to have several desired properties-high mechanical stability, long range lateral fluidity, and a thickness corresponding to a ...

Proteomics of Membrane Proteins
2003Publisher 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

The cell membrane and membrane proteins
2018This chapter talks about biological membranes that have a lipid bilayer structure made up of a variety of different lipids held together by noncovalent bonds. It shows that lipids are arranged with their hydrophobic tails pointing to the middle of the bilayer and their hydrophilic sections to the outside.

Microseparation of membrane proteins
Journal of Separation Science, 2009AbstractMembrane 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 ...

Structures of membrane proteins
The Journal of Membrane Biology, 1978The 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.

Crystallization of Membrane Proteins
2013The 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.
