Papain, a thiol protease was shown to utilize 5(4H)-oxazolinones of peptides as acyl donors in peptide segment condensations. The effectiveness of this methodology is illustrated by the successful coupling of oxidized insulin B chain (30 residues) to angiotensin III (7 residues) in 59% yield.
木瓜蛋白酶,一种硫醇蛋白酶,在肽段缩合中显示出利用5(4H)-恶唑啉酮作为酰基供体。该方法的有效性通过氧化胰岛素B链(30个残基)与血管紧张素III(7个残基)的成功偶联以59%的产率得以说明。
