[NMR study of beta-structures in the compact non-native states of globular proteins]

By the high resolution NMR method was made comparative research of carboanhydrase B, alpha-lactalbumin and apomyoglobin in a molten globular state. It is shown that though in an observed spectra the typical signals at 5.7-5 ppm, responding to the signals of alpha-CH protons of the beta-structure, method of spin diffusion proves that after all is taking place in carboanhydrase B and alpha-lactalbumin, that corresponds with the data of CD.
