Comparisons of NMR spectral quality and success in crystallization demonstrate that NMR and X-ray crystallography are complementary methods for small protein structure determination

The correlation among the NMR spectral quality and the effectiveness in structure identification by x-ray crystallography is evaluated for 159 prokaryotic and eukaryotic proteins that are already checked to evade the proteins that give either polydisperse or aggregated illustrations. The results show that both NMR and the X-ray crystallography methods give similar structural details and both can be used to get optimum accuracy.
