TROSY NMR Spectroscopy of Large Soluble Proteins.

TROSY NMR Spectroscopy of Large Soluble Proteins.

TROSY NMR Spectroscopy of Large Soluble Proteins.

Top Curr Chem. 2011 Sep 17;

Authors: Xu Y, Matthews S

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 methyl-TROSY have been shown to be effective for supramolecular systems as large as about 1 MDa. In this chapter we review the available methods for labelling different kinds of methyl groups and the assignment strategies in very large protein systems. Several proteins are selected as examples to show how NMR helps to reveal the details of structure, interaction and dynamics of these proteins.

Three-dimensional deuterium-carbon correlation experiments for high-resolution solid-state MAS NMR spectroscopy of large proteins Three-dimensional deuterium-carbon correlation experiments for high-resolution solid-state MAS NMR spectroscopy of large proteins Abstract Well-resolved 2Hâ??13C correlation spectra, reminiscent of 1Hâ??13C correlations, are obtained for perdeuterated ubiquitin and for perdeuterated outer-membrane protein G (OmpG) from E. coli by exploiting the favorable lifetime of 2H double-quantum (DQ) states. Sufficient signal-to-noise was achieved due to the short deuterium T 1, allowing for high repetition rates and enabling 3D experiments with a 2Hâ??13C transfer step in a reasonable time....	nmrlearner	Journal club	0	11-01-2011 01:52 AM

Selective 1H-13C NMR spectroscopy of methyl groups in residually protonated samples of large proteins Selective 1H-13C NMR spectroscopy of methyl groups in residually protonated samples of large proteins Abstract Methyl 13CHD2 isotopomers of all methyl-containing amino-acids can be observed in residually protonated samples of large proteins obtained from -glucose/D2O-based bacterial media, with sensitivity sufficient for a number of NMR applications. Selective detection of some subsets of methyl groups (AlaÎ², ThrÎ³2) is possible using simple â??out-and-backâ?? NMR methodology. Such selective methyl-detected â??out-and-backâ?? NMR experiments allow complete assignments of threonine Î³2...	nmrlearner	Journal club	0	01-09-2011 12:46 PM
TROSY-selected ZZ-exchange experiment for characterizing slow chemical exchange in large proteins TROSY-selected ZZ-exchange experiment for characterizing slow chemical exchange in large proteins Abstract A TROSY-selected ZZ-exchange experiment is described for measuring slow chemical exchange rates by monitoring the TROSY component of 15N longitudinal magnetization. Application of the proposed pulse sequence to the cadherin 8 N-terminal extracelluar domain demonstrates that enhanced sensitivity is obtained, compared to a previously described TROSY-detected ZZ-exchange sequence (Sahu et al. J Am Chem Soc 129: 13232â??13237, 2007), by preserving the TROSY effect during the mixing...	nmrlearner	Journal club	0	01-09-2011 12:46 PM
Recent advances in segmental isotope labeling of proteins: NMR applications to large proteins and glycoproteins Recent advances in segmental isotope labeling of proteins: NMR applications to large proteins and glycoproteins Abstract In the last 15 years substantial advances have been made to place isotope labels in native and glycosylated proteins for NMR studies and structure determination. Key developments include segmental isotope labeling using Native Chemical Ligation, Expressed Protein Ligation and Protein Trans-Splicing. These advances are pushing the size limit of NMR spectroscopy further making larger proteins accessible for this technique. It is just emerging that segmental isotope...	nmrlearner	Journal club	0	01-09-2011 12:46 PM
