Two new derivatives of butyrolactone I were isolated from Aspergillus terreus IFO 4100, and the structures were determined. A metabolic pathway from phenylalanine to butyrolactone I was established by administration of potential intermediates to growing or resting cells of Aspergillus terreus IFO 8835 and by enzymatic studies. Three enzymes involved in the biosynthesis were identified.
从土曲霉 IFO 4100 中分离出了丁内酯 I 的两种新衍生物,并确定了其结构。通过向赤曲霉 IFO 8835 的生长或静止细胞施用潜在的中间产物以及酶学研究,建立了从苯丙氨酸到丁内酯 I 的代谢途径。确定了参与生物合成的三种酶。
