Default Solution NMR Spectroscopy Provides an Avenue for the Study of Functionally Dynamic Molecular Machines: The Example of Protein Disaggregation.

Solution NMR Spectroscopy Provides an Avenue for the Study of Functionally Dynamic Molecular Machines: The Example of Protein Disaggregation.

Solution NMR Spectroscopy Provides an Avenue for the Study of Functionally Dynamic Molecular Machines: The Example of Protein Disaggregation.

J Am Chem Soc. 2015 Dec 11;

Authors: Rosenzweig R, Kay LE

Abstract
Solution-based NMR spectroscopy has been an important tool for studying the structure and dynamics of relatively small proteins and protein complexes with aggregate molecular masses under approximately 50 kDa. The development of new experiments and labeling schemes, coupled with continued improvements in hardware, has significantly reduced this size limitation, enabling atomic resolution studies of molecular machines in the 1 MDa range. In this perspective some of the important advances are highlighted in the context of studies of molecular chaperones involved in protein disaggregation. New insights into the structural biology of disaggregation obtained from NMR studies are described, focusing on the unique capabilities of the methodology for obtaining atomic resolution descriptions of dynamic systems.

13 CHD 2 ??CEST NMR spectroscopy provides an avenue for studies of conformational exchange in high molecular weight proteins Abstract An NMR experiment for quantifying slow (millisecond) time-scale exchange processes involving the interconversion between visible ground state and invisible, conformationally excited state conformers is presented. The approach exploits chemical exchange saturation transfer (CEST) and makes use of 13CHD2 methyl group probes that can be readily incorporated into otherwise highly deuterated proteins. The methodology is...
