to catalyze non-natural reactions remains underexplored. This paper reports a new biocatalytic strategy for the one-pot synthesis of unnatural α-amino acids. Engineered variants of dual-function Vitreoscilla hemoglobin were found to efficiently catalyze N–H insertion and C–H sp3 alkylation, providing moderate to excellent yields (57%–95%) of unnatural α-amino acid derivatives and turnover numbers (1425–2375)
尽管关于血红素蛋白定向进化的研究工作已经十分成熟且不断增长,但血红素蛋白催化非自然反应的潜力仍未得到充分探索。本文报道了一种用于一锅合成非天然α-氨基酸的新生物催化策略。双功能玻璃颤菌血红蛋白的工程变体被发现能够有效催化 N-H 插入和 C-H sp 3烷基化,提供中等至优异的非天然 α-氨基酸衍生物产率 (57%–95%) 和周转数 (1425–第2375章)
