Cadmium-113 nuclear magnetic resonance studies of bovine insulin: two-zinc insulin hexamer specifically binds calcium

JL Sudmeier, SJ Bell, MC Storm, and MF Dunn

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.
