Abstract

Recently it has been convincingly demonstrated that 30 triple-resonance NMR provides a practical alternative for obtaining sequential resonance assignments in larger proteins ( 1, 2). This approach requires a set of five or six 30 NMR experiments that correlate the various protein backbone nuclei. Details regarding the mechanisms and technical implementations of these experiments have been described previously ( 3- 5). Two of the experiments used in this approach correlate backbone Hα and Cα resonances with either the intraresidue carbonyl resonance (CO) or the 15N resonance of the succeeding residue and are referred to as HCACO and HCA(CO)N, respectively. The present Communication describes a modification of these experiments which optimizes their sensitivity and removes the F1 antiphase character of correlations.
