Abstract
Two modifications to sensitivity-enhanced gradient-selected TROSY-based triple-resonance NMR experiments are proposed that reduce the overall duration of the pulse sequences and minimize radiation damping effects on water-flipback solvent suppression. The modifications are illustrated for the HNCO–TROSY experiment, but are applicable to all triple-resonance experiments that detect proton magnetization after a reverse polarization transfer step from a 15N spin. The methods are applied to yeast triosephosphate isomerase, a symmetric dimer with 248 amino acid residues per monomer.
