Solution NMR studies of polytopic ?-helical membrane proteins.
Curr Opin Struct Biol. 2011 Jul 18;
Authors: Nietlispach D, Gautier A
NMR spectroscopy has established itself as one of the main techniques for the structural study of integral membrane proteins. Remarkably, over the last few years, substantial progress has been achieved in the structure determination of increasingly complex polytopical ?-helical membrane proteins, with their size approaching ~100kDa. Such advances are the result of significant improvements in NMR methodology, sample preparation and powerful selective isotope labelling schemes. We review the requirements facilitating such work based on the more recent solution NMR studies of ?-helical proteins. While the majority of such studies still use detergent-solubilized proteins, alternative more native-like lipid-based media are emerging. Recent interaction, dynamics and conformational studies are discussed that cast a promising light on the future role of NMR in this important and exciting area.

Abstract Membrane proteins represent up to 30% of the proteins in all organisms, they are involved in many biological processes and are the molecular targets for around 50% of validated drugs. Despite this, membrane proteins represent less than 1% of all high-resolution protein structures due to various challenges associated with applying the main biophysical techniques used for...

Signals between a cell and its environment are often transmitted through membrane proteins; therefore, many membrane proteins, including G protein-coupled receptors (GPCRs) and ion channels, are important drug targets. Structural information about membrane proteins remains limited owing to challenges in protein expression, purification and the selection of membrane-mimicking systems that will...

Membrane proteins are usually solubilized in polar solvents by incorporation into micelles. Even for small membrane proteins these mixed micelles have rather large molecular masses, typically beyond 50000 Da. The NMR technique TROSY...

Translational diffusion coefficients and catalytic activities were measured for the integral membrane protein diacylglycerol kinase (DAGK) in a variety of types of detergent micelles. Despite the structural diversity of the detergents examined, the translational diffusion coefficients observed for DAGK...
