Practical considerations over spectral quality in solid state NMR spectroscopy of soluble proteins.
J Biomol NMR. 2013 Aug 30;
Authors: Fragai M, Luchinat C, Parigi G, Ravera E
Abstract
Great theoretical and methodological advances are pushing the limits of resolution and sensitivity in solid state NMR (SSNMR). However, sample preparation remains a critical issue for the success of an experiment. The factors affecting spectral quality in SSNMR samples are discussed, examining cases encountered in the literature and presenting new experimental data. A discussion on resolution and sensitivity in sedimented solutes is framed in this context.

Abstract
Solid-state NMR spectroscopy proved to be a versatile tool for characterization of structure and dynamics of complex biochemical systems. In particular, magic angle spinning (MAS) solid-state NMR came to maturity for application towards structural elucidation of biological macromolecules. Current challenges in applying solid-state NMR as well as progress achieved...

Abstract
Solution nuclear magnetic resonance spectroscopy is usually only used to study proteins with molecular weight not exceeding about 50 kDa. This size limit has been lifted significantly in recent years, thanks to the development of labelling methods and the application of transverse-relaxation optimized spectroscopy (TROSY). In particular, methyl-specific labelling and...

Transmembrane helices are more uniform in structure than similar helices in water soluble proteins. Solid state NMR of aligned bilayer samples is being increasingly used to characterize helical membrane protein structures. Traditional spectroscopic methods have difficulty distinguishing between helices with i to i + 3...

Recording of four-dimensional (4D) spectra for proteins in the solid state has opened new avenues to obtain virtually complete resonance assignments and three-dimensional (3D) structures of proteins. As in solution state NMR, the sampling of three indirect dimensions leads per se to long minimal measurement time. Furthermore,...

Protein alignment using cellulose nanocrystals: practical considerations and range of
Abstract Cellulose nanocrystals (CNCs) form liquid crystals in aqueous solution that confer alignment to macromolecules and permit the measurement of residual dipolar couplings. CNCs possess many attractive features as an alignment medium. They are inexpensive, non-toxic, chemically inert, and robust to denaturants and temperature. Despite these advantages, CNCs are seldom employed as an alignment medium and the range of their applicability has not yet been explored. We have re-examined the use of CNCs in biomolecular NMR by analyzing the effects concentration, ionic strength, and...
