that involve modular type I polyketide synthases (PKSs) are proven strategies for the synthesis of polyketides. In general however, such strategies are usually limited in scope and utility due to the restricted substrate specificity of polyketide biosynthetic machinery. Herein, a panel of chemo-enzymatically synthesized acyl-CoA's was used to probe the promiscuity of a polyketide synthase. Promiscuity
涉及模块化I型聚酮化合物合酶(PKS)的组合生物合成方法被证明是合成聚酮化合物的策略。然而,一般而言,由于聚酮化合物生物合成机械的受限制的底物特异性,这种策略通常在范围和用途上受到限制。在此,使用一组化学酶促合成的酰基-CoA's来探测聚酮化合物合酶的混杂。解剖滥交决定因素,发现KS对多种扩展剂单元具有显着的耐受性,而AT可能会区分生产有机体天然的扩展剂单元。我们的数据为未来酶工程的研究提供了清晰的蓝图,并通过采用各种体内方法为利用扩展剂单位混杂性奠定了基础 聚酮化合物多元化策略。
