Citreoviridin (1) belongs to a class of F1-ATPase β-subunit inhibitors that are synthesized by highly reducing polyketide synthases. These potent mycotoxins share an α-pyrone polyene structure, and they include aurovertin, verrucosidin, and asteltoxin. The identification of the citreoviridin biosynthetic gene cluster in Aspergillus terreus var. aureus and its reconstitution using heterologous expression in Aspergillus nidulans are reported. Two intermediates were isolated that allowed the proposal of the biosynthetic pathway of citreoviridin.
黄绿青霉素(1)属于一类由高度还原型聚酮合酶合成的F1 - ATP酶β亚基抑制剂。这些强效霉菌毒素具有α - 吡喃多烯结构,包括金褐霉素、疣孢菌素和黄绿青霉素。本文报道了在土曲霉金黄色变种中黄绿青霉素生物合成基因簇的鉴定以及利用构巢曲霉中的异源表达对其进行的重构。分离出了两种中间体,据此提出了黄绿青霉素的生物合成途径。
