A methyl-TROSY based 13C relaxation dispersion NMR experiment for studies of chemical exchange in proteins
Abstract
A methyl Transverse Relaxation Optimized Spectroscopy (methyl-TROSY) based, multiple quantum (MQ) 13C Carr-Purcell-Meiboom-Gill (CPMG) relaxation dispersion NMR experiment is described. The experiment is derived from the previously developed MQ 13Câ??1H CPMG scheme (Korzhnev in J Am Chem Soc 126: 3964â??73, 2004) supplemented with a CPMG train of refocusing 1H pulses applied with constant frequency and synchronized with the 13C CPMG...

A methyl-TROSY based 13C relaxation dispersion NMR experiment for studies of chemical exchange in proteins
A methyl Transverse Relaxation Optimized Spectroscopy (methyl-TROSY) based, multiple quantum (MQ) ^(13)C Carr-Purcell-Meiboom-Gill (CPMG) relaxation dispersion NMR experiment is described. The experiment is derived from the previously developed MQ ^(13)C-¹H CPMG scheme (Korzhnev in J Am Chem Soc 126: 3964-73, 2004) supplemented with a CPMG train of refocusing ¹H pulses applied with constant frequency and synchronized with the ^(13)C CPMG pulse train. The optimal ¹H 'decoupling' scheme...

Abstract
Long-lived conformational states and their interconversion rates critically determine protein function and regulation. When these states have distinct chemical shifts the measurement of relaxation by NMR may provide us with useful information about their structure, kinetics and thermodynamics at atomic...

[NMR paper] General expressions for R1? relaxation for N-site chemical exchange and the special case of linear chains
General expressions for R1? relaxation for N-site chemical exchange and the special case of linear chains
Publication date: January 2017
Source:Journal of Magnetic Resonance, Volume 274</br>
Author(s): Hans Koss, Mark Rance, Arthur G. Palmer</br>
Exploration of dynamic processes in proteins and nucleic acids by spin-locking NMR experiments has been facilitated by the development of theoretical expressions for the R 1 ? relaxation rate constant covering a variety of kinetic situations. Herein, we present a generalized approximation to the chemical exchange,...

Abstract
Seeing the invisible: A 13 CO NMR chemical exchange saturation transfer (CEST) experiment for the study of "invisible" excited protein states with lifetimes on the order of 5-50 ms has been developed. The 13 CO chemical...
