biosynthesis of ansatrienin (mycotrienin) has been studied. [sup 13]C- and [sup 2]H-labeled samples of shikimic acid were used to probe the stereochemistry of processing the cyclohexane ring of shikimic acid and to establish the fate of all the precursor hydrogens in this transformation. A sample of [2-[sup 13]C]shikimic acid was fed to Streptomyces collinus Tu 1982, and [sup 13]C in the resulting ansatrienin
环己烷甲酸部分在 ansatrienin (mycotrienin) 的生物合成中的形成已被研究。[sup 13]C-和[sup 2]H-标记的莽草酸样品用于探测处理莽草酸环己烷环的立体化学,并确定该转化中所有前体氢的命运。[2-[sup 13]C]莽草酸样品被加入 Streptomyces collinus Tu 1982,发现所得 ansatrienin 中的 [sup 13]C 仅位于 C-36。在 Ansatrienin 的生物合成样品的水解中,伴随环己烷甲酸的 1-环己烯甲酸在 C-2 处而不是在 C-6 处带有 [sup 13] C 标记。[2-[sup 2]H]-、[3-[sup 2]H]-、[4-[sup 2]H]、[2,5-[sup 2]H[sub 2]]-的样本, [2,3,4,5-[sup 2]H[sub 4]]-, 和[6-[sup 2]H[sub 1]]莽草酸被喂给S
