Cervimycin C is the major component of an antibiotic complex produced by Streptomyces tendae HKI-179 consisting of a tetracycline-type aglycon, six tridesoxysugars and a rare dimethylmalonyl moiety. The biosynthetic origin of cervimycin was studied by molecular studies and feeding experiments, which reveal that the dimethylmalonate unit is not derived from malonate, but from valine.
宫颈霉素C是由天蓝色链霉菌HKI-179产生的一种抗生素复合物的主要成分,该复合物由四环素型苷元、六个十三脱氧糖和一个罕见的二甲基丙二酰部分组成。通过分子研究和饲喂实验对宫颈霉素的生物合成起源进行了研究,结果表明二甲基丙二酸酯单元并非来源于丙二酸,而是来源于缬氨酸。
