The total and chemoenzymatic synthesis of the depsipeptide natural product seongsanamide E, 3, is described. The synthetic C-terminal N-acetylcysteamine thioester of linear natural product 1 was macrolactonized by the excised recombinant purified seongsanamide thioesterase (Sgd-TE) domain, generating 3. Sgd-TE also effects the ring opening of 3. Chemical synthesis provided 3 through a macrolactamization
描述了缩肽天然产物 seongsanamide E, 3的总合成和化学酶合成。线性天然产物1的合成 C-末端N-乙酰半胱胺硫酯被切除的重组纯化的城山酰胺硫酯酶 (Sgd-TE) 结构域大环内酯化,产生3。Sgd-TE 也影响3的开环。化学合成通过大环内酰胺化策略提供了3 。这项工作证实了3的生物合成,并证明了 Sgd-TE 作为生物催化剂的能力。
