Three-dimensional nuclear magnetic resonance spectroscopy for the assignment of protein structure with one carbon and two hydrogen dimensions.
Notes:
  1. Magnetization is exchanged between all hydrogens using the nuclear Overhauser effect before being transferred to neighbouring A13A2213C nuclei and then back to A1A221H for detection.
  2. The spectrum is used to obtain restraints for structure calculations.
