Fooling with substrate recognition: Guanidinophenyl (OGp) esters were utilized as potential substrate mimetics for papain‐induced dipeptide synthesis under aqueous conditions. Surprisingly, modeling studies instead revealed unprecedented enzyme‐specific activation, applicable to nearly all amino acids.
具有底物识别功能的傻瓜:胍基苯基(OGp)酯被用作在水性条件下木瓜蛋白酶诱导的二肽合成的潜在底物模拟物。令人惊讶的是,建模研究显示出空前的酶特异性激活作用,几乎适用于所有氨基酸。
