Abstract
The relationship of membrane protein function and the surrounding lipid bilayer goes far beyond simple hydrophobic interactions. At least from the 1980s, it is speculated that a certain fluid lipid state may be important not only for the lateral diffusion of membrane proteins (MPs) but also for modulating the catalytic activity of MPs (Lenaz. Bioscience Rep 7 (11):823-837, 1987). Indeed, acyl chain length, hydrophobic mismatch, and lipid headgroups are determinants for enzymatic and transport activities of MPs (Dumas et al. Biochemistry 39(16):4846-4854, 2000; Johannsson et al. Biochim Biophys Acta 641(2):416-421, 1981; Montecucco et al. FEBS Lett 144(1):145-148, 1982; Martens et al. Nat Struct Mol Biol 23(8):744-751, 2016). Moreover, it is speculated that changes in membrane lipid dynamics are important in the field of thermosensation (Vriens J, Nilius B, Voets T, Nat Rev Neurosci 15:573-589, 2014). Atomic insights into lipid-mediated modulation of membrane protein dynamics would therefore provide new insights with the potential to fundamentally extend our understanding on dynamic lipid-protein interdependencies.This chapter describes the expression and purification of nanodiscs assembled from membrane scaffold protein (MSP) as well as the expression and purification of the outer membrane protein X (OmpX). Subsequently, the incorporation of OmpX into MSP-derived nanodiscs is explained in detail. The chapter concludes with the setup of nuclear magnetic resonance (NMR) relaxation experiments and the extraction of relaxation rates for OmpX and the surrounding lipids.

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...

Abstract
Solid-state NMR studies of sedimented soluble proteins has been developed recently as an attractive approach for overcoming the size limitations of solution NMR spectroscopy while bypassing the need for sample crystallization or precipitation (Bertini et al. 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...
