Measurement of ψMet in f-MLF-OH by the double-quantum 15N–13C–13C–15N experiment (38). (a) Experimental and simulated dephasing of the Met C′–Cα double-quantum coherence under the C′–N and Cα–N dipolar couplings. The best simulation yields a torsion angle of ±157° ± 1°. (b) rmsd between the NCCN simulation and experiment for the Met residue, calculated as a function of ψ.
