The present invention relates to enzymatic oligopeptide synthesis in the N→C direction, in particular to a process for the preparation of an optionally N-protected oligopeptide C-terminal alkylester comprising the step of reacting the corresponding optionally N-protected oligopeptide C-terminal carboxyamide with an alkyl alcohol, preferably methanol, in the presence of a peptide amidase. The formed C-terminal alkylester can subsequently be used for the coupling with another amino acid residue or oligopeptide. Therefore, inventors have found a very advantageous process for the preparation of oligopeptides.
本发明涉及N→C方向的酶促寡肽合成,特别是涉及一种制备可选择进行N保护的寡肽C端烷基酯的方法,包括以下步骤:在肽酰胺酶的存在下,将相应的可选择进行N保护的寡肽C端羧酰胺与烷基醇(优选
甲醇)反应。形成的C端烷基酯随后可用于与另一个
氨基酸残基或寡肽耦合。因此,发明人发现了一种非常有利的制备寡肽的方法。
