摘要: A novel method for producing glucagon is provided. The method comprises the steps of, preparing a fusion protein shown by the following formula:
X-Glu-Glucagon (I)
wherein X is a leader sequence of 70-170 amino acids, Glu is a glutamic acid residue, and Glucagon represents the amino acid sequence of glucagon, and
treating the fusion protein with an enzyme that specifically hydrolyzes the peptide bonds at the carboxyl termini of the glutamic acid residues, resulting in cleavage of the fusion protein.摘要翻译: 提供了一种生产胰高血糖素的新方法。 该方法包括以下步骤:制备由下式表示的融合蛋白:X-Glu-胰高血糖素(I),其中X是70-170个氨基酸的前导序列,Glu是谷氨酸残基,而胰高血糖素代表氨基 酸性序列,并用特异性水解谷氨酸残基的羧基末端的肽键的酶处理融合蛋白,导致融合蛋白的切割。
