The use of solution NMR labeling techniques in solving structures of membrane proteins by solid state in-cell NMR

Abstract

Solid state in-cell NMR is an excellent technique to study membrane proteins. The in-cell aspect resolves the requirement of solubilization and reconstitution steps, resulting in a far more straightforward expression scheme. And the solid state aspect removes the need of fast tumbling membrane proteins. In this study different labeling schemes are investigated for their use for structural assignment of membrane proteins by in-cell solid state NMR. By combining clever labeling schemes with in-cell solid state NMR, this technique can prove to be very useful in filling in the large gap of structural data for membrane proteins.
