A peptide with C-terminal proline amide is produced by reacting in aqueous solution a protein substrate having C-terminal prolyl-leucine, prolyl-isoleucine, prolyl-valine, or polyl-phenylalanine with carboxypeptidase Y in the presence of amonia. The ammonia is preferably generated by the aqueous reaction of an ammonium salt and an alkali. An example of the peptide product is human calcitonin.
在水溶液中,具有 C 端脯氨酰-亮氨酸、脯氨酰-异亮氨酸、脯氨酰-缬氨酸或多酰基苯丙氨酸的蛋白质底物与羧肽酶 Y 在氨的存在下发生反应,生成具有 C 端脯氨酸酰胺的多肽。 氨最好是由铵盐和碱在水溶液中反应生成的。 多肽产品的一个例子是人降钙素。
