甲基转移酶(MTases)形成了一个大家族的酶,它可以甲基化一系列不同的目标,从三种主要的生物聚合物到小分子。大多数mtase使用辅助因子S -腺苷- 1 -蛋氨酸(AdoMet)作为甲基源。近年来,人们在AdoMet类似物的开发上做出了巨大的努力,目的是转移除简单甲基以外的部分。目前存在两大类AdoMet类似物:双活化分子和基于叠氮嘧啶的分子,每一类都采用不同的方法来实现转烷基化而不是转甲基化。在这篇综述中,我们讨论了利用AdoMet依赖性mtase和AdoMet类似物标记和功能化生物分子的各种策略。我们介绍了AdoMet类似物的合成路线,它们在生物环境中的稳定性以及它们在转烷基化反应中的应用。最后,对AdoMet类似物在生物学研究、(epi)遗传学和纳米技术中的潜在应用进行了展望。
Methyltransferases (MTases) form a large family of enzymes that methylate a diverse set of targets, ranging from the three major biopolymers to small molecules. Most of these MTases use the cofactor S‐adenosyl‐l‐Methionine (AdoMet) as a methyl source. In recent years, there have been significant efforts toward the development of AdoMet analogues with the aim of transferring moieties other than simple methyl groups. Two major classes of AdoMet analogues currently exist: doubly‐activated molecules and aziridine based molecules, each of which employs a different approach to achieve transalkylation rather than transmethylation. In this review, we discuss the various strategies for labelling and functionalizing biomolecules using AdoMet‐dependent MTases and AdoMet analogues. We cover the synthetic routes to AdoMet analogues, their stability in biological environments and their application in transalkylation reactions. Finally, some perspectives are presented for the potential use of AdoMet analogues in biology research, (epi)genetics and nanotechnology.
