FISH CALCITONIN DERIVATIVE, PROCESS FOR ITS PREPARATION, AND GENE SYSTEM THEREFOR

摘要

This derivative comprises 33 amino acids wherein glycine is added to the C-terminal of fish calcitonin composed of 32 amino acids. This derivative itself has a biological activity and can be converted into natural fish calcitonin composed of 32 amino acids wherein proline in the C-terminal is amidated, by treating it in a conventional manner.
