Phospholipid bicelles are valuable membrane model systems to study membrane proteins by NMR and other physicochemical techniques. The range of bicelle compositions that are compatible with uniaxial alignment of the lipid bilayers in a magnetic field is still limited with regard to the addition of large amounts (>20%) of cholesterol and/or sphingolipids. Here, we demonstrate that n-dodecyl-?-D-melibioside (DDMB), which was recently introduced as a detergent to produce...

Abstract
Cholesterol (Chol) is vital for cell function as it is essential to a myriad of biochemical and biophysical processes. The atomistic details of Chol's interactions with phospholipids and proteins is therefore of fundamental interest, and NMR offers unique...

Multidimensional oriented solid-state NMR experiments enable the sequential assignment of uniformly 15N labeled integral membrane proteins in magnetically aligned lipid bilayers
Multidimensional oriented solid-state NMR experiments enable the sequential assignment of uniformly 15N labeled integral membrane proteins in magnetically aligned lipid bilayers
Abstract Oriented solid-state NMR is the most direct methodology to obtain the orientation of membrane proteins with respect to the lipid bilayer. The method consists of measuring 1H-15N dipolar couplings (DC) and 15N anisotropic chemical shifts (CSA) for membrane proteins that are uniformly aligned with respect to the membrane bilayer. A significant advantage of this approach is that tilt and azimuthal...
