Diumycin, janiemycin, nisin, and subtilin inhibited peptidoglycan synthesis catalyzed by particulate enzyme systems from Bacillus stearothermophilus and Escherichia coli. All of these, except for nisin, also induced accumulation of the lipid intermediate in peptidoglycan synthesis. Concentrations required for 50% inhibition of peptidoglycan synthesis were less than 0.1 mug/ml for diumycin and in the range of 10 to 100 mug/ml for janiemycin, nisin, and subtilin in both organisms. The discrepancy between the extremely low concentration of diumycin required to inhibit the in vitro system from E. coli and the much higher concentration required to inhibit growth of the organism is noteworthy.
迪尤霉素、杰尼霉素、乳链菌肽和枯草菌素抑制了嗜热脂肪芽孢杆菌和大肠杆菌的颗粒酶系统催化的肽聚糖合成。除乳链菌肽外,所有这些物质还诱导了肽聚糖合成中脂质中间体的积累。在两种生物体中,抑制肽聚糖合成50%所需的浓度,迪尤霉素小于0.1微克/毫升,杰尼霉素、乳链菌肽和枯草菌素在10至100微克/毫升范围内。抑制大肠杆菌体外系统所需的迪尤霉素浓度极低,而抑制该生物体生长所需的浓度则高得多,这种差异值得注意。
