摘要: Pulse sequences are presented for the measurement of3JC′Cγ and3JNCγ scalar couplings allCγ containing residues in15N,13C uniformly labeled proteins. The methodsdescribed based on quantitative J correlation spectroscopy pioneered byBax and co-workers [Bax et al. (1994) Methods Enzymol., 239, 79–105].The combination of 3JC′Cγ coupling constants allows theassignment discrete rotameric states about χ1 torsion angle in cases where such exist or, alternatively,facilitates establishment noncanonical χ1conformations or presence averaging. methods areapplied to a 1.5 mM sample staphylococcal nuclease.
