摘要：

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 N-15 spin. The methods are applied to yeast triosephosphate isomerase, a symmetric dimer with 248 amino acid residues per monomer, (C) 1999 Academic Press.
