Structure determination of large proteins by solution state NMR is challenging due to spectral overlap. Here the authors present a labeling strategy using 2-13C and 3-13C pyruvate as carbon source for E. coli, which increases the effective resolution of triple-resonance HNCA experiments and helps to overcome this problem.
