Abstract
By use of cadmium-113 nuclear magnetic resonance spectroscopy, a specific calcium ion binding site has been identified in the bovine two-zinc insulin hexamer. This site is composed of six glutamyl carboxylate groups clustered in the center of the hexamer, and is distinct from the normal zinc ion binding sites.
摘要
通过使用镉-113核磁共振光谱法，在牛的双锌胰岛素六聚体中鉴定出了一个特定的钙离子结合位点。该位点由聚集在六聚体中心的六个谷氨酰羧基组成，与正常的锌离子结合位点不同。
