Default Methyl groups as probes of supra-molecular structure, dynamics and function

Methyl groups as probes of supra-molecular structure, dynamics and function


Abstract The development of new protein labeling strategies, along with optimized experiments that exploit the label, have significantly impacted on the types of biochemical problems that can now be addressed by solution NMR spectroscopy. Here we describe how methyl labeling of key residues in a highly deuterated protein background has facilitated studies of the structure, dynamics and interactions of supra-molecular particles. The methyl-labeling approach is briefly reviewed, followed by a summary of applications to three different molecular machines so as to illustrate the types of questions that can now be addressed. Areas where future innovations will lead to yet further improvements are highlighted as well.

Optimal methyl labeling for studies of supra-molecular systems
Abstract Selective methyl labeling combined with HMQC spectroscopy that exploits a TROSY effect in 13CH3 spin systems has significantly extended the utility of solution NMR spectroscopy in studies of high molecular weight particles. Herein we compare the utility of 13CH3- versus 13CHD2-labeling of Ile, Leu, Val probes in supra-molecular systems through quantification of relative signal-to-noise ratios in optimized spectra of highly deuterated, 13CH3- and 13CHD2-labeled samples of the half proteasome (α7α7, 360 kDa). It is shown that the sensitivity of spectra recorded on Ile, Leu, Val...
