Lipid-helix interactions in membrane receptors.
The integration of the transmembrane (TM) proteins in the lipid bilayer depend on lipid-protein interactions. The few crystal structures known for multiple membrane spanning proteins suggest a basic form composed of bundles of a-helices that pack together. In the membrane helix-helix and helix-lipid interaction define the helix arrangement in the folded receptor. Thus, the lipid-protein interac...
متن کاملSpecific protein-lipid interactions in membrane proteins.
Many membrane proteins selectively bind defined lipid species. This specificity has an impact on correct insertion, folding, structural integrity and full functionality of the protein. How are these different tasks achieved? Recent advances in structural research of membrane proteins provide new information about specific protein-lipid interactions. Tightly bound lipids in membrane protein stru...
متن کاملProtein-lipid interactions in the photosynthetic membrane.
In each case the complexes were suspended in 20rn~-Tris/HCl (pH 8.0)/0.1% LDAO (v/v). The circles indicate where the recording spectrophotometer stopped and the spectra were continued point by point in another machine. (a) Complexes from strain 7750 grown at 2000k: 0, type 1 B800-850; 0, RC-B880. (b) Complexes from strain 7050 grown at 4001~: 0, type 2 B800-850; this spectrum was raised to make...
متن کاملOn the importance of hydrodynamic interactions in lipid membrane formation.
Hydrodynamic interactions (HI) give rise to collective motions between molecules, which are known to be important in the dynamics of random coil polymers and colloids. However, their role in the biological self-assembly of many molecule systems has not been investigated. Here, using Brownian dynamics simulations, we evaluate the importance of HI on the kinetics of self-assembly of lipid membran...
متن کاملModulation of membrane surface curvature by peptide-lipid interactions.
Recent reports on the interaction of cardiotoxin and melittin with phospholipid model membranes are reviewed and analyzed. These types of peptide toxins are able to modulate lipid surface curvature and polymorphism in a highly lipid-specific way. It is demonstrated that the remarkable variety of effects of melittin on the organization of different membrane phospholipids can be understood in a r...
