摘要
With the isomorphous difference Fourier method and the restrained least-squares re-finement technique, the crystal structure of 4- zinc bovine insulin in space group R<sub>3</sub> wasdetermined. The final crystallographic residual is 0. 19 at 1. 9A resolution. Based on therefined model, the structural mechanism for prolonged action of 4- zinc insulin is discussed.
