Abstract
The pulse sequence of a new constant-time 3D triple-resonance experiment, ct-HA[CAN]HN, is presented. This experiment delineates exclusively scalar connectivities and uses 13C alpha-15N heteronuclear two-spin coherence to overlay the chemical shift evolution periods of the 13C alpha and 15N nuclei, thereby providing the four resonance frequencies of the alpha-proton, the alpha-carbon, the amide nitrogen, and the amide proton of a given amino acid residue in three dimensions. This experiment promises to be a valid alternative to 4D experiments, providing the same information on intraresidue polypeptide backbone connectivities in 13C-15N-double-labeled proteins.Entities:
