Three-dimensional nuclear magnetic resonance spectroscopy for the assignment of protein structure with one nitrogen, and two hydrogen dimensions.
Notes:
  1. Magnetization is transferred from the side-chain hydrogen nuclei to their attached A13A2213C nuclei. Then isotropic A13A2213C mixing is used to transfer magnetization between the carbon nuclei. From here, magnetization is transferred to the carbonyl carbon, on to the amide nitrogen and finally the amide hydrogen for detection.
  2. Requires A15A2215N and A13A2213C labelling.
  3. Useful spectrum for obtaining hydrogen side-chain assignments.
