Probing the excited-state chemical shifts and exchange parameters by nitrogen-decoupled amide proton chemical exchange saturation transfer (HN(dec)-CEST).
Abstract
CEST-NMR spectroscopy is a powerful tool for probing the conformational dynamics of
macromolecules. We present a HN(dec)-CEST experiment that simplifies the relaxation
matrix, reduces fitting parameters, and enhances signal resolution. Importantly, fitting
of HN(dec)-CEST profiles enables robust extraction of exchange rates as well as excited-state
chemical shifts and populations.

Protein-protein interactions play a pivotal role in the regulation of various cellular
processes. The formation of higher order protein complexes is frequently accompanied
by extensive structural remodeling of the individual components, varying from domain
re-orientation to induced folding of unstructured elements. Nuclear Magnetic Resonance
(NMR) spectroscopy is a powerful tool for macromolecular structure determination in
solution. It has the unique advantage of being capable of elucidati
