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...

[U. of Ottawa NMR Facility Blog] CEST - Chemical Exchange Saturation Transfer
CEST - Chemical Exchange Saturation Transfer
Chemical Exchange Saturation Transfer (CEST) is a technique where one resonance, in slow exchange with a second resonance, is saturated with a selective low power pulse followed by a hard non-selective 90° pulse. The intensity of the second resonance is then diminished due to the transfer of saturation from the first resonance as the result of chemical exchange. The figure below demonstrates this for a 25 mM solution of salicylic acid in H2O/D2O buffered at pH 7. ...

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...
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...
