Default Measurement of Ligand-Target Residence Times by (1)H Relaxation Dispersion NMR Spectroscopy.

Related Articles Measurement of Ligand-Target Residence Times by (1)H Relaxation Dispersion NMR Spectroscopy.

J Med Chem. 2016 Dec 08;59(23):10788-10793

Authors: Moschen T, Grutsch S, Juen MA, Wunderlich CH, Kreutz C, Tollinger M

Abstract
A ligand-observed (1)H NMR relaxation experiment is introduced for measuring the binding kinetics of low-molecular-weight compounds to their biomolecular targets. We show that this approach, which does not require any isotope labeling, is applicable to ligand-target systems involving proteins and nucleic acids of variable molecular size. The experiment is particularly useful for the systematic investigation of low affinity molecules with residence times in the micro- to millisecond time regime.

Quantitative measurement of exchange dynamics in proteins via 13 C relaxation dispersion of 13 CHD 2 -labeled samples
Quantitative measurement of exchange dynamics in proteins via 13 C relaxation dispersion of 13 CHD 2 -labeled samples Abstract Methyl groups have emerged as powerful probes of protein dynamics with timescales from picoseconds to seconds. Typically, studies involving high molecular weight complexes exploit 13CH3- or 13CHD2-labeling in otherwise highly deuterated proteins. The 13CHD2 label offers the unique advantage of providing 13C, 1H and 2H spin probes, however a disadvantage has been the lack of an experiment to record 13C...

Date: 2011-05-31 Detailed understanding of protein function and malfunction hinges on the ability to characterize transiently populated states and the transitions between them. Here, we use 15N, , and 13CO NMR R2 relaxation dispersion to investigate spontaneous unfolding and refolding events of native apomyoglobin. Above pH 5.0, dispersion is dominated by processes involving fluctuations of the F-helix region, which...

Using relaxation dispersion NMR spectroscopy to determine structures of excited, invisible protein states
Using relaxation dispersion NMR spectroscopy to determine structures of excited, invisible protein states D. Flemming Hansen, Pramodh Vallurupalli and Lewis E. Kay Journal of Biomolecular NMR; 2008; 41(3); pp 113 - 120 Abstract: Currently the main focus of structural biology is the determination of static three-dimensional representations of biomolecules that for the most part correspond to low energy (ground state) conformations. However, it is becoming increasingly well recognized that higher energy structures often play important roles in function as well. Because these conformers...
