activity extends to the efficient and stereoselective intermolecular transfer of carbenes to olefins, heterocycles, aldehydes, and amines. Not only is this a report of carbene transferase activity in a completely de novo protein, but also of enzyme-catalyzed ring expansion of aromatic heterocycles via carbene transfer by any enzyme.
通过构建体内组装的、催化能力强的过氧化物酶 C45,我们最近证明了简单的、从头设计的血红素蛋白的催化潜力。在这里,我们展示了 C45 的酶活性延伸到卡宾到烯烃、杂环、醛和胺的高效和立体选择性分子间转移。这不仅是关于完全从头蛋白质中卡宾转移酶活性的报告,而且是通过任何酶的卡宾转移酶催化芳族杂环扩环的报告。
