Assembly of phospholipid nanodiscs of controlled size for structural studies of membrane proteins by NMR.
Nat Protoc. 2018 Jan;13(1):79-98
Authors: Hagn F, Nasr ML, Wagner G
Abstract
Suitable membrane mimetics are crucial to the performance of structural and functional studies of membrane proteins. Phospholipid nanodiscs (formed when a membrane scaffold protein encircles a small portion of a lipid bilayer) have...

When proteins misfold, accumulate and clump around insulin-producing cells in the pancreas, they kill cells. Now, researchers, including University of Michigan biophysicists, have obtained a structural snapshot of these proteins ...

[NMR paper] Solubilization of Membrane Proteins into Functional Lipid-Bilayer Nanodiscs Using a Diisobutylene/Maleic Acid Copolymer
Solubilization of Membrane Proteins into Functional Lipid-Bilayer Nanodiscs Using a Diisobutylene/Maleic Acid Copolymer
Once removed from their natural environment, membrane proteins depend on membrane-mimetic systems to retain their native structures and functions. To this end, lipid-bilayer nanodiscs that are bounded by scaffold proteins or amphiphilic polymers such as styrene/maleic acid (SMA) copolymers have been introduced as alternatives to detergent micelles and liposomes for in vitro membrane-protein research. Herein, we show that an alternating diisobutylene/maleic acid...

Optimizing nanodiscs and bicelles for solution NMR studies of two β-barrel membrane proteins
Abstract
Solution NMR spectroscopy has become a robust method to determine structures and explore the dynamics of integral membrane proteins. The vast majority of previous studies on membrane proteins by solution NMR have been conducted in lipid micelles. Contrary to the lipids that form a lipid bilayer in biological membranes, micellar lipids typically contain only a single hydrocarbon chain or two chains that are too short to form a bilayer. Therefore,...

Nanodiscs vs. Macrodiscs for NMR of Membrane Proteins.
Biochemistry. 2011 Sep 21;
Authors: Park SH, Berkamp S, Cook GA, Chan MK, Viadiu H, Opella SJ
Abstract
It is challenging to find membrane mimics that stabilize the native structure, dynamics, and functions of membrane proteins. In a recent advance, nanodiscs have been shown to provide a bilayer environment compatible with solution NMR. Increasing the lipid to "belt" peptide ratio expands their diameter, slows their reorientation...
