This data article supports the research article entitled “Maximally Asymmetric Transbilayer Distribution of Anionic Lipids Alters the Structure and interaction with Lipids of an Amyloidogenic Protein Dimer Bound to the Membrane Surface”[1]. We describe supporting data on the binding kinetics, time evolution of secondary structure, and residue-contact maps of a surface-absorbed beta-amyloid dimer protein on different membrane surfaces. We further demonstrate the sorting of annular and non-annular regions of the protein/lipid bilayer simulation systems, and the correlation of lipid-number mismatch and surface area per lipid mismatch of asymmetric lipid membranes.

Lipid bilayer-bound conformation of an integral membrane beta barrel protein by multidimensional MAS NMR Lipid bilayer-bound conformation of an integral membrane beta barrel protein by multidimensional MAS NMR Abstract The human voltage dependent anion channel 1 (VDAC) is a 32Â*kDa Î²-barrel integral membrane protein that controls the transport of ions across the outer mitochondrial membrane. Despite the determination of VDAC solution and diffraction structures, a structural basis for the mechanism of its function is not yet fully understood. Biophysical studies suggest VDAC requires a lipid bilayer to achieve full function, motivating the need...	nmrlearner	Journal club	0	01-30-2015 12:15 PM

Proc Natl Acad Sci USA 108(26):10396â??10399, 2011). Inspired by the potential benefits of this method, we have investigated the ability to sediment lipid bilayer...	nmrlearner	Journal club	0	01-12-2015 11:31 PM
