真菌芳香聚酮化合物构成了一个具有生物活性的天然产物大家族,由迭代聚酮化合物合酶(NR-PKS)的非还原基团合成。它们的不同结构源于活性酶结合的聚-β-酮中间体的选择性酶促修饰。迭代PKS如何控制起始单元选择、聚酮化合物链引发和延伸、中间折叠和环化、组装过程中的选择性氧化还原或修饰反应以及产物释放是迭代催化的核心机制问题。这篇综述重点介绍了对这些问题的最新见解,特别关注真菌芳香聚酮化合物的生物合成程序,并与细菌中的相关生物合成过程进行了比较。
Fungal aromatic polyketides constitute a large family of bioactive natural products and are synthesized by the non-reducing group of iterative polyketide synthases (NR-PKSs). Their diverse structures arise from selective enzymatic modifications of reactive enzyme-bound poly-β-keto intermediates. How iterative PKSs control starter unit selection, polyketide chain initiation and elongation, intermediate folding and cyclization, selective redox or modification reactions during assembly, and product release are central mechanistic questions underlying iterative catalysis. This review highlights recent insights into these questions, with a particular focus on the biosynthetic programming of fungal aromatic polyketides, and draws comparisons to the allied biosynthetic processes in bacteria.
