肽天然产物生物合成的最新创新揭示了大量以前未表征的生化反应,这些反应在合成生物学中具有潜在的应用。其中,蓝菌素值得注意,因为这些肽的 N 端和 C 端受到大环化的保护。在这里,我们使用一种新型双功能酶 AgeMTPT 通过在其游离 N 端和 C 端连接异戊二烯基和甲基来保护线性肽。使用这种肽保护酶与其他模块化生物合成酶结合,我们描述了天然产物铜绿酰胺B的全合成和线性氰菌素天然产物的生物合成。我们的研究有助于定义大环化的酶促机制,提供反对转肽的水排斥假说的证据,并支持动力学不稳定性假说。
Recent innovations in peptide natural product biosynthesis reveal a surprising wealth of previously uncharacterized biochemical reactions that have potential applications in synthetic biology. Among these, the cyanobactins are noteworthy because these peptides are protected at their N- and C-termini by macrocyclization. Here, we use a novel bifunctional enzyme AgeMTPT to protect linear peptides by attaching prenyl and methyl groups at their free N- and C-termini. Using this peptide protectase in combination with other modular biosynthetic enzymes, we describe the total synthesis of the natural product aeruginosamide B and the biosynthesis of linear cyanobactin natural products. Our studies help to define the enzymatic mechanism of macrocyclization, providing evidence against the water exclusion hypothesis of transpeptidation and favoring the kinetic lability hypothesis.
