Abstract
The horse heart apocytochrome c was investigated by high resolution 1H-NMR. The secondary chemical shifts of 1H-NMR spectra are not observed, which is typical for disordered molecules. However NOE is characterized by the appearance of spin diffusion which decreases with a temperature increase. The presence of spin diffusion assumes an existence of rigid sites and thus some ordered conformation of the molecule.
摘要
采用高分辨率¹H-NMR对马心脱辅基细胞色素c进行了研究。¹H-NMR谱未观察到二级化学位移，这是无序分子的典型特征。然而，NOE的特征是自旋扩散的出现，其随温度升高而降低。自旋扩散的存在表明存在刚性位点，因此分子存在一些有序构象。
