The present invention relates to a process for the amidation of C-terminal esters or acids of peptide substrates in solution-phase synthesis of peptides, comprising amidating one or more peptide substrates comprising C-terminal esters or acids using the protease subtilisin in any suitable form in the presence of an ammonium salt derived from an acid having a pKa above 0.
This process is useful in the production of protected or unprotected peptides.
本发明涉及一种在溶液相合成肽时对肽底部酯或酸的羧基进行酰胺化的方法,包括使用
蛋白酶亚胺肽酶在任何合适的形式下,在存在来自pKa高于0的酸的
铵盐的情况下酰胺化一个或多个包含底部酯或酸的肽底物。该方法对于生产受保护或未受保护的肽是有用的。
